It does end well for any gambler who thinks they can easily multiply their gambling money won through gambling more. I don't feel pity for those kinda people who allowed their greed to control them to gamble consistently without thinking of "what if" I gamble, and it didn't work as planned to win more.

That being said, this is a lesson to learn for those who think they can actually bet to win more without having a rethink about their actions that gambling losses are more than wins
