If a gambler does not want to lose or lose, then it is better to stop gambling because in gambling the biggest win can only be obtained by the dealer, because in gambling there are loses and wins and there are profits and losses so only we ourselves can determine everything.
You need to know that all gamblers definitely don't want to lose, they will always have an optimistic mindset that they can win every game.
But unfortunately the thoughts that gamblers have to be able to win continuously are not balanced with what they are doing. They do bet in games but don't do what can make them win or at least minimize losses such as doing research or testing games to get the right strategy. Good.
Many gamblers play or bet randomly or carelessly so it is difficult to win or beat the dealer.
Even though it's true what you said that in gambling only bookies have big wins, I'm sure there must be some loopholes to be able to beat it.
