The Trump collection seems to be a mix of Trading Cards and PFP collection.
Each NFT has a set of traits like the main image of Trump, the face, the background and the hat.
Imagine you have a set for each trait with different variants and then having images generated automatically with a combination of each one of these traits.
You may see an NFT with the same image of the person, but there won't be an NFT with the same set of all 4 traits.

But there are a lot of collections where you have multiples of each NFT.
Think about an NFT version Topps MLB cards (which by the way exists https://wax.atomichub.io/market?collection_name=mlb.topps&order=desc&sort=price)
You can buy a pack which is an NFT and then open it which will add to your wallet 5 cards and you can get duplicates.
But each rarity has a limit on the number of duplicates that can be minted
