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.
I dont beleive that lotto is good to play with money which you need or with bank which you use for gambling because it isnt skilled game where you can use your own skills like in poker tables.
