People who manages to gain some profits are the ones who can control their selves because if a person know that after so many wins, there is a time that they will lose their bets. I think, there is no problem with the stats because a player can't change the data on the website. So, people sometimes gain profits from gambling since it's all about the luck.
Yes, you are right. Some people who can win in gambling games, they have control of themselves, but many of them are losing their winning because they are too greedy to chase another winning. And if that is related to the stats, I think the stats automatically wrote once a gamblers win the games. But I believe that some gamblers can really win in the gambling games, they can stop gambling when they win, they can be able to control themselves once they win or lose, so they can still have the money.
