Well, that's actually a huge win for these lucky gamblers but the question now is: How come they show just their winning and not how many times they have lost to the platform?. Believe me, the same games they play is almost the same we do but unlucky like them. The truth is, these guys always have a huge lose during gambling, the amount of funds they can afford to lose no one on this forum can afford such.
Though, as a mini gambler I have risk my funds both those that belongs to me and partially on my care on gambling but haven't gotten much win for myself like the ones OP just shared. This still make me believe that, gambling is all about luck for those who win big.
