I majored in statistics undergraduate and being able to derive and prove the gamblers ruin problem is one of the requirements. At 50/50 it's your money over your plus house's money. And it gets drastically worse as soon as the house gets even a slight edge. I wasn't the casino's target anyways as I saw it was a waste of time and I loathe all the time wasted walking past the gaming area to even see music at a done here like a Hard Rock.

Edit, my school is the top link when I searched for a reference, I guess they included it after the casinos went into Atlantic City. Generalized Gambler's Ruin Problem - Rutgers Math https://sites.math.rutgers.edu/~zeilberg/EM20/GamblersRuin.p...
