Types of Casino Poker

Hello, I was wondering if anyone had information regarding what types of poker are played in casinos (in North America and globally)?

Obviously Texas Hold’Em is the most popular, but I have seen other casinos have Omaha Hold’Em and Seven Card Stud. But are there any others (played in casinos)?

I’ve anecdotally read that it’s easier to make money in Omaha than Texas because the players are less skilled on average. Wondering if that’s the same for Seven Card Stud or other games. I have never played poker in a casino because I am not good (yet), but I’m interested in learning about Omaha and maybe other variants played in casinos if anyone has resources that they would recommend.

Thanks very much for reading and have a great Thursday
