I think only a few people stop gambling at two things
1. When they make Money
2. When they lose Money
But still, there is no guarantee for some people will start gambling after making money but this will lead to loos at last.
No, I do not agree with you. People do not stop gambling in these two situations especially when they make some money. The greed of winning money will never come to an end the winners will try again to win more. I think that addicted gamblers will stop gambling when he has nothing left for gambling or when he dies. These are the two situations for stopping gambling.
