Moral of the story - you can never be rich with gambling, and even if you end up being "rich" - you would lose the whole lot in no time ... only the house wins because the house has an edge.
I don't think so. There are a lot of people who win in lottery with millions in our country. Most of them, they remain rich because they were able to establish their own business and stop betting in lottery because they know it's only once in a lifetime luck.
I do not think so. He might have earned this huge stakes of dollars but literally no one would ever spend again all the amount earned on the table. People are rational and rather prefer to put in less than they make in gambling. This is the rule of the table according to the experienced people. And yes many people who win big stay rich long times for they prefer to put back the money in good and certain projects.
