Gambler's Ruin

The video discusses a gambling scenario where two players with finite $5 bills play a game of chance with a 50% win probability. It explains that one player will eventually lose all their money, highlighting a common gambling fallacy. The video uses a coin toss to illustrate that each event is independent, with a consistent 50% chance of heads or tails, debunking the idea of 'luck' in repeated outcomes.
