Investing > Gambling??

[tvta]

Ok so I know much about gambling but little about investing. My pops hates gambling but is an investaholic, and claims investing > gambling. For those of you out there who know both pretty well, which one is more +EV? I just graduated college and now have a full time job that pays very decent for entry level. Should I invest mass amounts or add to my bankroll mass amounts(given I am a solid winning player)
