I don't think this helps me understand the difference.
hydrochorlic acid is dissolved HCl in water, while HCl gas is HCL itself.
The hydrogen atoms cannot dissociate from the molecules when a gas. Meaning that there are no H+ ions present, so it does not behave like an acid.However, when in aqueous form the hydrogen atoms can dissociate from the molecules. Meaning that H+ ions are present and so it behaves like an acid.Hope this cleared up any confusion :)

Also got A* in all my mocks and the science were a big help because of this page. I basically wrote down these notes and used CGP book guide and revised them by sticking them round house and placing them in places I go regularly so its easy.
