No i am not rich from gambling and i don't know anyone that is rich from it
Most of them only seem to be millionaires, but behind all that thing sits a big, big debt at the banks. They haven't started from $100 (and those who did... Were extremely lucky), most of them borrowed a lot of money and tried their 50/50 odds.
Well, that is because they are treating gambling as a business and they want to invest on themselves rather than trusting to others. I would definitely commend those people who succeeded in gambling because only few can do that.
