In events of jackpot maybe but, you have to be that gambler that is extremely lucky and might have only gambled for a very limited time or have not gambled for long and doesn’t go back to gambling ever.
Do we really have these kind of people? Many gamblers after winning the jackpot often comes back to gamble again, perhaps on a different casino, it doesn’t matter and many of them have lost so much in the past. These are really rare to the point we could only speculate on it else, there isn’t any winning of the casino.
