To be honest I do not think that it is possible to turn gambling into a profitable something gambling is not mend for the user to be able to win a profit. It is a game it is you versus the casino, so making a activity out of it would not work.
Indeed, its hard to believed on that things. Because if gambling really giving profitable activity I guess majority of the people nowadays are trying to apply in any company instead they do gamble in the gambling sites. But that's the fact happen now, which means it maybe profitable only for the rich people only few of them.
