I don't know if there's something issue with regulation happening on why we see most of casino tokens struggle to be added on big exchange.
I also tried to view some tokens which is under gambling category
https://coinmarketcap.com/view/gambling/ have big volumes and I see Arcadeum which got $30m volume which also been listed on Bitget,gate.io,HTX and Lbank which is somehow a decent exchange.
I thought we do not have any examples of Casino token listing on centralized exchanges. But when you mentioned arcadeum, I was interested in checking. When I click on the link to their website, it says something is wrong and forwards me to this URL
BTW, I also checked that Shuffle actually listed their token on XT.com, which is a centralized exchange. That proves I was wrong with my initial statement. The casino tokens can be listed on exchanges if they pay the listing fees. Some exchanges may allow listing them.
