SSH is often paired with an application, a shell, but that doesn't
make it an application layer protocol. SSH establishes and manages a
transport layer connection between the client and server, over which
you can tunnel most other transport layer protocols.
You are right to a certain extent, but not enough to
make a good argument. I can't say wikipedia prides
itself on universal correctness, but still consult these
articles to clear any doubts about what layer ssh
may or may not belong to:
