I do not relate luck to gambling because it is so much evident that the games and odds in gambling (but odds betting) are programmed in a way that gamblers will eventually lose. Gamble more and lose is the reality. Win and do not gamble for that time wise decision. Also with the little amount of money I am using to gamble, it is like that because there is nothing like luck to me in gambling. Most people will lose while 1 out of thousands of people would win which are the lucky ones. I am not saying there is no lock in gambling but understand what I mean.
If the odds are programmed for gamblers to lose and you end up winning it's actually luck, the system was designed to favour the house and anytime you manage to make profit it's just as a result of being on the right timing. Not many believe in luck but it actually exists, when it comes to casino gambling, there are no systems that can put you in profit as a gambler, you can only stake and hope to get lucky. But here's the tricky part of it, you can only get lucky when you win and don't play again because if you try to get the same result you would end up losing.
