I agree, which is why I think it’s absurd the casino is able to sue him to get the money back. I’d make the same argument with the slot machine - it’s your equipment, you are the idiots who created the conditions under which you lost money. I could imagine someone actually tampering with a slot machine, but I think the equivalent of that with cards would be actually manipulating the cards.
Fun story: I remember reading a story about a couple of guys who won on very early digitized slot machines by figuring out which pseudo-random pattern the slot machines were using and doing a bunch of math. Basically they could tell by watching about 10 plays in a row whether the machine had positive EV over the next 100 plays or so. So they walked around casinos watching people play, and then when people got up from machines they either took the seat or didn’t depending on whether the machine was in a good state. They won about $200k in a week, and a casino manager took them aside and said to them: You can keep the money, but tell us what the hell you are doing.
