A clear example of this is Axie Infinity, which became popular for its P2P a few years ago. I think a casino would benefit a lot from this, since profits are guaranteed in P2P by charging a slight percentage to its players. It also has other factors that can make them attractive and profitable, such as sales of skin, tools, weapons, although it is an artistic and mechanical challenge to include this type of games so that it does not stray from the essence of a casino.

I think it's possible for a casino to have 100% original content that attracts and keeps its players engaged.

And regarding licenses, this is always done prior to launch. They can be temporary or permanent exclusives, depending on the developer and the contracts signed.
