It's just luck that permits him to win. No one knows the random result. There's no assurance that by spinning for numbers of times
will grant you the win. It's something that no one can control aside from luck that it's not always beside of anyone of us. It's really something
that you will always remember when you hit that luck and take that huge amount of wins.
By the way, good luck to you! If same luck comes up maybe it's your turn to take the winning one,
Keep trying, while you still have that chance!
Random results are so random that people sometimes confuse the randomness of the results. For example the dice game world had this for years now, nearly a decade long and people are still confused about the results. Let's say you gambled on 50% chance to win, and gambled 20+ times, and you lost them all, you said under 50 but it was over 50 for back to back 20 times, people think that 21st has a bigger chance to be correct. That has been mathematically wrong for a decade and people never understood it, each and every single bet has the same chance, just because it has been under 50 for 20 times doesn't make the 21st one any different, that's the same chance.
This is what makes people lose money, and this is what martingale got it wrong but some reason people still end up believing this wrong myth and lose money because of it, quite interesting situation.
