I think gambling is not going to make the rich may be contrary gambling will make no money or run out of money for gambling and also makes people become addicted
It can make someone rich depending on his situation and event. There are people who are betting with lottery and manage to be lucky for their entire life and becomes rich for winning the pot once in their life time. There are also some people who are winning in lottery for a couple or even more and that's making them rich.
still there is a few people that getting rich from gambling because they have a perfect luck in gambling itself but for normal people, i think getting rich from gambling is difficult. beside of luck, we need to have a good experience in gambling and we have to control ourself and don't be greedy when we can winning very often than other people.
