The seventh needs a distance check

A leading tone lies a semitone below the tonic. B is the leading tone to C. In A natural minor, G lies a whole tone below A and is called the subtonic instead.

These names identify positions and relationships. Calling degree 5 dominant does not mean every chord containing that note is automatically a dominant-seventh chord.
