If it's a game of luck yes, we mostly need luck but what if it's a game of skill? We can still be able to win as long as we are skillful and have only a little or no luck at all. It's possible for a skillful players to win at most times and the only way for them to be defeated is when there are players that is more skillful than them.

But indeed that it's better to stop once the start and the middle of the game is mostly losses as it can be a sign that we are not lucky for the day. I've tried to continue many times thinking that later games are going to be good but no., I only lose all my balance. I admit that until now, I still got tempted to continue sometimes. Gambling is truly powerful.
