I once found an algorithm named "gambling ruin" which means that when a player competes with an opponent richer than him he'll end up losing all his funds.
Well in that sense it makes a lot of sense, because it's true that the more money a Person has the more opportunity they have to play and win, but you have to understand something, a person who has more money can do a lot more than a person who has little money , and if that person who has a lot of money plays with small amounts then they will have a much greater chance of playing and even winning, but a person who has a lot of money can Play with such High Amounts that it Doesn't matter if they lose the first few times , if they win with a bet they are Capable of winning back Everything they have lost, that's the Difference.
There's always a difference between a person with good amount of money to risk compared to a person with lesser one, though the changing factor is how a gambler will decide after winning or after recovering and same with how the topic said, withdrawal will be your best tools if you want something decent after playing a game, it's important to make good and wise decision to quit afterm making a good pick or a good bet and win.
