I don't believe they're all of them; most of them include some sort of strategy, which eliminates the possibility that NFT games are a form of gambling. Consider Axie Infinity: it's a skill-based game with a chance element in the form of cards, critical hits, and opponent skill, but it's not gambling.
Skill-based at first maybe,,, but like most games like nowadays the grinder will always win. Spend more time (or more money) and you get more cards, more skills,,, and are always stronger than the guy who only logs in once per day.
If this is not gambling, that is, putting in your time in the hopes of gaining that <1% super rare skill on a loot box, I do not know what is
