This sounds a lot like a faucet but for NFTs. I don't find this very exciting. There was a bubble of NFTs that started to burst a few months ago, and realistically, 99% are going to have a value of 0 or very close to 0 in the next few years.
I think NFT in casinos is not really concerned with its artistic value, it will function more than just collectibles which of course only plays a passive role in the casino industry.

If there isn't any utility to their NFTs, not a lot of people will even bother wanting those NFTs. If these things can be converted into something that can be used on the casino, perhaps gamblers will be proud to have that item on them just to trade for perks and whatnot.
Overall I don't think that these NFT integration will make a big difference on casinos and the overall gambling experience but that's just me.
In the Op article mention about the privilege of NFT holders which equates players with a certain VIP level in the casino. Despite the offerings, I doubt that this NFT will be able to entice players. In general gamblers prefer to make money that is rather "extreme", fueling their adrenaline.
