If you happen to be at a casino, make exactly one bet in your lifetime and there’s a significant chance you’ll end up ahead. On average you’ll be out money but we don’t live out every possibility and average them.

However again the odds of breakeven just reduce the cost of play they aren’t the only thing people get for their money.
