That's why we have what's called 'public bets' and 'sharp bets.' Public bets tend to lose more often, which is why only a few individuals or groups genuinely succeed in gambling.
We should be looking for that group, but it won't be easy. They can completely hide themselves from the public. And it is true that the public's bets tend to lose, and the bets of that group most often win.
Most of the legitimate groups are those that know which games are fixed. If they only rely on their skills, there's still no assurance that a particular bet will win. They might win most of the time, but I don't think they would encourage disciplined bankroll management, as it may not help them maximize their profit. I believe the larger the bets bettors place, the more they can earn, similar to a commission based on winning bets. However, if a bet loses, they bear no responsibility.
Finding such groups is indeed difficult, so it's often better to believe in yourself and learn from your mistakes. Who knows, you might improve and eventually become profitable.
It hard to find those kinds of groups who knows what game are fixed, I'm just hearing it and thinking that it's just a rumor and whoever part of that group they for sure maximizing the potential win, if does exist, there are a huge amount of money that involves, imagine how many people you need to pay for you to manipulate the game.
Better to stick with your own knowledge and understanding instead of aiming for joining or paying with such offers, which is still not a guarantee that they can convert a win for your money.
So the best way is just focusing on the little knowledge someone can predict for himself because in the game of betting nobody is perfect one could Actually improve and figure out a strategy that could actually favor him instead of relying on betting group.
