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.
Some of people are earning from gambling by just working as mods,referral earners and lucky pot winner and that made them earning for their gambling activity, But if they just doing some solely gambling i dont think that they can earn more profits in their long time spending on some gambling sites out there since we all know gamblers are always the losers in the end of the game.
