No matter how much I want to believe that there is no such safe way, we cant ignore the fact that the experience gambler win more than the new gamblers, there must be a reason to that.
If not wining but there must be a way or instinct to lose less in gambling that u get over years of experience.
If we talk about skill based game like sports betting and poker, so I have to agree that experienced gambler will win more than beginners. But in case of playing on pure luck based game like dice, slots, lottery etc so we cant say the same. Here there is no gambler who win more than the other based on how long they have played the game because the results based on luck.
