For example, I could release one million ERC-20 tokens and then trade with them. They will all have the same value, and I cannot mint any more. With NFTs (ERC-721), we can mint any number of cryptography tokens, and each will have an owner. Each of these can have its own value, or be pinned to a physical asset or identity. For example, as a tutor, I could assign each of my students to an NFT, and where we link the NFT to the student. Overall, we create these with a smart contract, and where there is an "owner" of the creation of the tokens.
