Non-Fungible Crypto Tokens



I understand bitcoin and etherum and how they use blockchain but I cant seem to understand NFTs or Non-fungible tokens. I tried watching a video that explains what they are, but the more I do research the less I understand. So it can be a physical or virtual product that you hold on to that holds the same value of the amount of crypto you used to purchase it? But what is the point of this? Why would someone choose this over a vault or a decentralized finance app where they could receive interest? I am very confused by this and was hoping someone could dumb it down for me because I think I misunderstand the entire concept.
