After working there, i must say i respect anyone going into that business, it ain't as easy as some would like to think
I basically agree with this point
But we should not forget either about scams which just pretend to be "provably fair" casinos. As far as I remember, there were a few such cases discussed here in the past. Some were not outright scams but their bets were proven to be far from fair. Once it had become known with irresistible evidence provided, they had to close the shop. Some casinos were legit but their bankroll management sucked massively so it didn't take long for some whale to come and ruin them by betting big time and taking away all their money
