What is the difference between a bitcoin public key and a wallet address?

Public Keys are used to create wallet addresses. How that public key is created is independent of the bitcoin protocol.

Both the public and the private key are stored in the wallet software. It is possible to offload these to a cold wallet.

If all you have is the bitcoin address, without any other record on the chain, then it is not possible to retrieve the public key.
