I think any product's value greatly depends on the peer generated value.
This means, who you know and not what you know (or even what grand feat you do) will get you the ability to sell an NFT like this for this much.
It's a game of networking, and as stakes increase exponentially as market price builds momentum the more popular it is thought to be, the more it becomes as scarcity and exclusivity are key features of NFTs.
It's a living art of the dynamics of the value system of this world. Like when that one artist accidentally left their glasses on the floor of an exhibit and everyone crowded around it thinking it meant something.
Accumulated perceptual value. Humans are cultish in behaviour, always have been, always will be - there's a part of our brain dedicated to being in a cult and believing something is true just because those around us believe it - the value of things is no different and nor are NFTs.
So if you want to 'make' an NFT that looks valueless that makes this much money - it would be better to pick up a text book on group psychology, NLP and networking - than it would be to go to art school.
Good luck with your studies! Get out there and signal to the hill!
