yes it is true, but if luck is on our side, but if not? maybe we will just continue to bet using all strategies to minimize losses when betting and sometimes these strategies will be destroyed when we fight our own emotions when we lose at gambling.
any strategy that is carried out if we cannot commit ourselves to controlling emotions, it will only be in vain.
As said in War Games, a great movie from 1983:
"Strange game. The only way to win is not to play."
You can of course play to enjoy some fun, but maths tell you that you're not going to win in the long term.
