Sports betting - best strategies

I have two friends at sports who also launch express trains quite often,
but they can be collected from low-risk events with very low odds
and this is no longer 3 coins 50/50 ))))
and, for example, 6 coins with a 90% weighted eagle

That's the whole point, because of the bookmakers' inflated odds, the result should be much lower, that is, at the level of 9-10% instead of 12.5 for ideal conditions, but in reality I see a completely opposite picture, my friends often have express bets with odds of 8-12, they should at best be successful 1 out of 10. I don't understand what's going on...

There is a coin that we toss and count the number of heads and tails, let the conditions be ideal and out of a hundred times everything was equal, 50% each! Now we take three coins, what percentage will all three heads fall out? I got 12.5%, but in reality the percentage is much higher! I am calculating something incorrectly, explain to me where the mistake is and how such things are generally calculated!

At each step, we will consider possible options for all 3 coins. 0 - tails, 1 - heads
000
001
010
011
100
101
110
111
Or, to put it simply, N = 2^3 = 8
The variant where all three times the eagle came up (111) is only one out of eight, i.e. exactly 0.125 = 12.5%. On 100 throws the average number of all 3 eagles coming up will be 12.5. The number turned out to be fractional, but it doesn't matter. On 200 throws it will be 25 - no longer fractional. So you have it right.
Another thing is that the real quantity may differ from the average, both upwards and downwards. But if you repeat the experiment thousands of times (N throws per experiment), this percentage will tend to 0.125, and the quantity to 0.125 * N

Betting is a dead topic in the long run.
You need to win money first, and then withdraw it.
Any strategy has its drawbacks, which will lead to a drain in the long run.
There are really only 3 ways to supposedly beat the bookmaker:

1) Forks. Here, fork scanners are in action and simple forking between bookmakers gives you a little profit, no matter the events.
But. All fork bettors are cut very quickly and it literally becomes boring to keep money in 20-30 offices and do all this for the sake of a couple of percent of profit. In addition, any delay, a special glitch or your sluggishness and that's it - you put on one fork shoulder, and the second shoulder has already dropped the odds and you are in the minus. In addition, where to get hundreds of accounts with approvals (sometimes and videos) to constantly and normally earn on this hemorrhoid?
2) Value bets. Everything is clear here, you should find events in the line that you consider overvalued by the bookmaker. Those where the probability of the event you assume is higher than the bookmaker thinks. But firstly, such events in serious offices (they missed the line shift, bad software, etc.) are few, and in all sorts of homeless offices you will again not be paid anything for nothing, you will wait for these verifications for weeks and months, and then they will cut your account and that's it.
3) You are a genius analyst, you can estimate the probability better than teams of professional analysts in bookmakers. You beat the line at a distance and can afford to play in Pinnacle or SBObet, which allow pro players to play and do not cut accounts. But then you will never be found on this or any other similar forum))

I'm not talking about the options of all sorts of insiders or small market specialists. Yes, there are some, but how many are there? And decent offices almost never give detailed coverage of all sorts of 3 Irish leagues, and you can't earn much on P1-P2).

So bets are essentially the same roulette. Here -2.7 and "luck", which sometimes allows you to go up. And there the role of -2.7 is played by the bookmakers' margin, included in the odds. Only usually more than 2.7. 5-7, and the impudent ones have 10%.
There is no adaptive, of course, but it is also impossible to calculate the results (:

Alexey! Are you not a poker player from the GSM forum? They are also driving everyone crazy about negative expectation! The most famous cappers have earned hundreds of millions of dollars on sports and no roulette players can even come close, and the number of such people is much greater than successful roulette players! What you wrote reminds me of the conversations of ordinary people about the fact that it is impossible to make money in casinos and bookmakers, and all the strategies that you gave as an example are imposed on everyone on the Internet by bookmakers, which means they are not working! The most important weapon against bookmakers is statistics! The most accurate of all sciences! But what you need for successful sports betting is not on the Internet! You need to look for and collect it yourself, just like in roulette, no one will give you a ready-made recipe! As for withdrawing winnings, everything is very simple, do not get involved with bookmakers from the CIS, now the hottest trend is Asian offices, in the fight for the client they calmly allow you to make multi-million dollar bets and withdraw winnings, and European bookmaker sharks have not gone anywhere!
