I want to ask, do you believe in experts gambling predictions.
There's no 100% winning tickets games unless the individual giving you that prediction has a loophole in the casino and has got the game from game fixing. No individual can predict games and be sure that he'll win all, no expert brag about his ability to predict games correctly. If he noticed how good he is, he'll make profits with it before he begins to share his games to others to win and he won't be doing it for free, he'll charge those interested in receiving the tickets some fees.
I don't think we should be believing some individuals that claims to be experts in betting, they can have few luck and win some of their games but no individual will win every time that they gamble. Gambling is a game of luck therefore when you're lucky you can always win. Play the games that you know very well to increase your chances of winning but don't believe anybody you see that they're expert in gambling.
