I prefer strategic gambling with amount that I can afford to lose. No gmabler become suddently rich by gmabling, let alone being billionaire. But, by running a gambling site, you can definitely be a billionaire. 
This comment is Superb and direct to the point... I totally agree with this... Instead of being a small time gambler, Try to run a gambling site, It would be more profitable...
Yes I totally agree only the gambling site owners or house itself are the one who are able to make billions of bucks.
And they are the one who are the only people who are fixing their lives with gambling.
Because they can earn from it.
