Sounds like your teacher would get along well with my last boss. (I only lasted there about three months, shock of shocks.) He was the head of the proofing team, and a walking dictionary (in the sense of knowing how to spell things), but his grammar was… shaky. He just didn’t understand a lot of how sentences actually worked, structurally, and I did, and it showed. (Imagine such meetings as me trying to explain why you would hyphenate “**all-day **sale” but not “it was on sale all day.”)
Still, there are smarter games to play, if you’re going to gamble. If you’re going with games that are purely RNG, you want to be playing craps, betting on the pass line with an odds bet on that.* Out of all the RNG games, that will get you closest to even odds with the house, since your odds bet pays out on the actual odds of the roll itself. It’s just the original pass line bet that favors the house, so you just stack the biggest possible proportion of your bet on the odds part of it.
*It’s been a while, so my terms may be wrong.
