On the other hand, yes, you have experienced it yourself that greed more often leads a gambler to regret than results that are in accordance with expectations, and that should be a valuable lesson for gamblers so as not to get caught in the same hole.
They always lose and get stuck in the same hole, because they refuse to control themselves, don't learn from their past mistakes and only put their greed first.
They will only regret it when there is no more money to bet which then finally makes them realize that it is out of bounds.
Regrets are always behind and they become very stressed.
Beginner luck or even professional players will have just the same chances, the only difference is the control of themselves.
Beginners don't have definite control because they are still trying to explore the game and betting, whereas professional players already know what they have to do.
