And this is the very definition of gambling, when we thought that we might have the decoded the unknown, and so we come up with this so called strategies. However, again, everything could have been luck after all and there are no secret sauce for success in gambling.
It's base on pure luck alone, others might argue that there are strategies and skills like poker, but still for me, if you are not lucky, even if you have all the skills in the world, you are going to lose in the end. So there are no experts here, and I agree that those who claimed to be as scammers.
Well, for games that have to do with skills, level of skill do contribute to chances of winning the game, as if we are to use an example, imagine playing poker with someone you are clearly more skillful than, but while the game is on, you deliberately refuse to take your turns, you discover that you amount or level of luck will save you from the loss, the other dude will beat you hands down even with your high level of skill and supposed luck.
So, lets not rule out or undermine the contribution of skill and knowledge in seeing that we win in games where this attributes are needed respectively speaking, they together in conjunction with luck, see that we come out as winners.
But for luck based games, it's purely based on luck as we all should know.
