Yes.
NFTs represent tangible items - digital image, sound, text, etc .
Compare this with coins/tokens which are non-tangible - do not associate with item or service.
I would include in this group - meme coins, DeFi tokens, and even bitcoin…
Regarding if NFTs are worth it - the value depends on promoters and community which defines what is good. Personally I find lots of crappy images sold as NFTs…
