Yes, it is possible. But we saw here a thread, when someone bet more than $1.000.000 with the odd less than 1.01 and lost it. There are no guarantee of winning in gambling, so some moment you can lose even with such odds.
No guarantee to win with 100% chance in gambling even you bet with low odds like 1.01.
Risk of losing all money by 1 bet with low odds and with all capital to meet 1 wager turn requirement for withdrawal is terrible. Why criminals must accept that risk if they have other choices like using mixers and pay mixing fees?
You must ask someone another about criminals risk. I saw here the thread with such a bet for more than $1.000,000 and i don`t know is it criminal or not. The same time if someone makes it the main income source, why someone can`t use it for laundering? I think that it is possible situation.
