@resjudicata I am going to disagree with you.
The physical casinos make you an offer where you will probably lose money, but you might win. The odds are published. The reason people take these bets is that losing $1 (or $10 or $100, depending on the person) doesn't hurt much, but winning $20 (or $200 or $2,000) would feel really good so people take the chance even though they know they have 3% - 10% chance of coming out ahead. At least in the US, there are occasional inspections to make sure the games aren't rigged.
The online casinos bury the $100k playthrough in the fine print and the algorithm knows your entire history. It sounds like there is no chance at all of coming out ahead in the end, even though people think they have some chance. Depending on the where the casino is located, I don't think it would be physically possible for anyone to inspect the 'games' to see if they are rigged or not.
tl:dr Physical casinos are a bad idea, but fail to meet the definition of a scam because they lack the element of deceit.
