At which stage (primary, secondary, tertiary, and quaternary) is protein a polymer and why?

I'm a student who's a bit confused since I've been taught that protein in primary stage is only a polypeptide.

All proteins have primary, secondary and tertiary structures but quaternary structures only arise when a protein is made up of two or more polypeptide chains. The folding of proteins is also driven and reinforced by the formation of many bonds between different parts of the chain.

The primary structure of a protein refers to the sequence of amino acids in the polypeptide chain.

Proteins are polymers made out of amino acids. So, proteins are polymers of amino acids.

A protein may be made up of 1 polypeptide chain, in which case the stage that the protein is a polymer is tertiary.

A protein may be made up of 2 or more polypeptide chains, in which case the stage that the protein is a polymer is quaternary.

Collagen, hemoglobin, antibodies, and enzymes are examples of proteins.
