Gambling are base in luck, we can not say that we are pro in gambling, gambling is are too hard to predict. So we need our luck is in our side. Even though some users have more experience on it but we can't say that he/she is a pro on that maybe he/she can win because there's a strategy but still it will not long last. So it's better to play safe cause there's no pro in gambling.
No matter how old a gambler he is, there is no strategy here, after all, everything depends on luck, so winning at gambling by applying strategy is completely wrong, if you keep winning a few games undefeated for a while, then there is no need to consider it as skill, it is definitely because of your good luck, so refrain from believing in wrong things like skill and strategy in gambling, everything is luck here and if there is no luck, you will definitely lose.
