Why are intermolecular HCl molecules among them not considered hydrogen bonds?

A hydrogen bond is the attractive force between one electronegative atom and a hydrogen covalently bonded to another electronegative atom. Doesn't this apply to hydrochloric acid?

It results from a dipole-dipole force with a hydrogen atom bonded to nitrogen, oxygen or fluorine.

Studying general chemistry? That statement was from wiki so basically, it's gotta involve one of those elements.

Youd expect it to because Cl is pretty electronegative, but chlorine is also a very large molecule, so it basically cant get close enough to the hydrogens to cause any particularly strong dipole, and the hydrogen has a high charge density so it deformes the large Cl into a fairly covelant bond.
