Gambling Limit

If money, introduced to the economy through abusing gambling exploit, was not the reason limit was set, then what?
I get limiting people when there was a variable giving you 100% win chance is the right thing, but if casino works as it should, any extreme wins will be compensated by extreme losses, so there is no reason to gambling limit existence.
So by saying that casino works as it was intended, and gambling limit is a must have thing, it’s bascally saying that “We are afraid of lucky people”, when the whole server is build on the idea of lootboxes and stuff you get from it. Lootbox = Gamble, where you can get exotic and get 100x profit from it.
