She should be doing cartwheels after hearing that you only spent 5 bills.
That sounds bad and not like something that has more to do with gambling than with drinking. Alcohol doesn't give good advices.I used to have a problem back in the day. Playing in games I had no clue about and also drinking while playing poker before I had ever read a poker book and spent any time studying the game. Most of my gaming troubles I believe had to do with alcohol problems.
I know plenty of degenerate gamblers though. One kid lost 40k at the blackjack tables that he owed to a bookie. Not sure how that one played out.
