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.
Sometimes I use to be very imaginative on how the outcome would be if actually the whole set up with odds in betting was something else like every team had an equal or the same odd. For sure the rate of wins would be more because on that note gambler wouldn't get to add more games especially when you are playing parley bets and sometimes it's because of the odds isn't just enough that we get to add some games which the odds are manipulated.
