When I would go to a casino, I had $20, and I played until either I lost it or came out with $100. Probably over time, I pretty much broke even.
Back in the 80s we had a weekly football pool at work one year....try as I may I couldn’t win for anything......last week of the regular season was the last week for the pool and low and behold I finally won......just enough to cover my losses for all previous weeks.....I knew then gambling was a suckers bet
