Those who firstly introduce anything does not mean that they are successful on that type of project. But regarding this case the project rollbit is successful. And it happens nit only for the introducing of nft on gambling but also for various aspects.
Rollbit had really got a good head start overall, specially on marketing in the first weeks of their website being up. It gained popularity as they have original games and other things newly implemented that we rarely seen (or don't see) on other gambling platform. Then this NFT came, more players and investment came as they see it only the first that has been done in the market.

In short, its pretty much the same as lottery and winner takes all. Here is the main catch, you can pool in either raw cash or NFT of your own choice and the winner takes it all. This lottery runs every 50 eth blocks and Rollbit will take up to 5% rake depending on the size of the pool
This is interesting. As of writing this post, the jackpot value is already at $6,200
