You said "buying tons of $20 scratch-off tickets". Of course I was referring to literally that. If you want to say gambling in general, no, not even that is correct. It can only be done where you mostly play against a complice and the house takes a small fixed cut. Nothing to do with lottery shit, that didn't make any sense at all.
The fact lottery tickets were one of the less practical examples does nothing to dispel the point that gambling is a commonly used method of money laundering, which was my point. Your point on one specific form of gambling might be valid but completely unmoving against the principle.
There is no need to have an accomplice, someone could just bet $20 an improbable lottery every time they sell a "hit", eventually they would win big and then have legal taxed income washed and only have to explain how they came up with $20 to end up with thousands in earnings. Who cares if they lose 20,30,50% to the house and taxes when they are happy to pay that to stay out of prison and making high margins.
In fact, watch videos of various change and counterfeit scammers, they quite often use the lottery tickets to launder their proceeds and as part of their crime.[]
