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.
But these type of people are much lesser among us they are only a few people who get to win a lottery. Most of the people lose in gambling and remain with nothing even those people who win once try to win some more money because they start believe that they can earn so they gamble again for the lottery and they lose back all of these money.
