There should be more to what you have posted here because if you are confident with your method then I doubt if you will waste your time in posting this thread here because you can just use that method anytime you want and earn the money that you like to get.
Most of those people who have successful method won't share it to anyone especially if it can ruin the method when there will be many that are going to use it or the platform owner where the method works will do something to counter their successful method that is why most of the genuine method are in silent mode or they are hiding it to themselves.
And if most of the people followed the method that OP is proposing and if it is legit and working 100%, there will be no casinos to open and serve the people. But for my experience in gambling, I haven't seen even 1 that has a game with players having 100 percent chance of winning. But if the game is an Esport and we really know a team which is really good, the chance of our bet to bet will be quite higher but still not 100 percent.
casino will start to cheat or invent a system that is hard to beat if that happens or there will be no more paid casinos but there will still be free to play casinos .
winning a gambler wins , isnt that consider a 100 percent win ? but if he loose with a closer result to win , that can be an example of 99 percent chance win or less .
