there are thousands of professional gamblers.. if not tons more then that.. but one of the huge advantages they get once they win millions is a million can produce a ton of income monthly off investments and if you can properly bankroll and obviously bet right (which pros do ) your practically gambling money without fear of loss.

plus all the endorsements pro poker players get..

either way investing as you go along is a huge key to success not many people just gamble all there money all the time theres alot more going on.
