or Rich people gamble just for show off to their friends or to attract girls to get into bed 
I do not think so . gambling is not something that should be shown. if we really rich then we will be silent. a rich from gambling would be smart to keep secret the amount of money he has. because the struggle, gambling makes a person stronger. and more eager to become richer. Yes. The more people become rich the more they want to become much more richer and richer. They will not tell anybody that they have the amount of money of a lots of digits.
They always want more , so no matter a gambler rich already or not they will remain gamble if they love to do gain profit .
Gambling is not about become rich only.
Sometimes rich people doesn't show that they have a lot of money, that they can gamble anytime that they wanted. And I think not all rich people doing gambling. because the other people that have a lot of profit/income doesn't want to lose it. They will continue doing business instead of gambling. They want to become more richer. Or to have much more income every month, much more higher than they have now.
Yes, not all rich people will gamble this is correct. Because there are a lot of Rich peoples are there in this world if they all play gambling means we see double of the casino's what we have now right. So here compare to rich people the poor people will play lot why because of money they need money so they will choose this easy method.
It is always depend on how rich people and poor people use their money, sometimes rich people getting poor by gambling, and sometimes the poor people much more have knowledge in gambling so they become rich eventually, but not all. This is just an example. because sometimes it's happening.
