Your dad’s a smart guy!

That’s the smart plan. Every time I’ve been to a casino (4 times I can recall) I had an amount set aside that I was prepared to lose and that would be it for me. A couple times I got ahead and just cashed out.

People have an inherent inability to assess probability. Even with “safer” games like black jack when your odds are a little closer to 50:50, people will keep pushing until they have no money left. Bet it all 4 times and there’s about a 94% chance you lose it all.
