2 conditions to be considered:

1️⃣    When an NFT does not have an underlying asset, for example, it is a collectible, the ownership right will be transferred within the transaction and the owner will now own the NFT wholly;
2️⃣    When an NFT has an underlying asset such as artwork or music, the ownership right in the NFT may be represented by an exclusive license or a limited license over the underlying asset depending on the contract.
It is important to take note that usually the buyer will get a limited license to use the NFT and ownership rights will not be transferred depending on the agreement.
