The hierarchy or the organizational set up of an advertising agency keeps both these profiles and do have a different scope of work as well as a profile for them.
A copywriter is a person who writes. This writing is of scripts of jingles for audio or video advertisement. This may be the text of a printed advt. material. The copywriter is responsible for composing the concept and bringing the words that make the best impact and create a brand of the advertised product.
The art director is the person who does an altogether different but comprehensive work than a copywriter. It is the art director who designs an advertisement of print or audio or video.
The art director is primarily the leader of the set up of shooting set where a TV or video commercial is shot. This way, a copywriter is someone who composes things in sync with the Director and Art Director's Concept and plan.

The degree of Bachelors in Mass Media aka mass communication or journalism and mass communication gives a foundation to the skill sets and knowledge to enter the media careers. There are specialisations offered through B.Sc and other technical degrees in the domain of mass media only where you may get more of direction and film-making learning.
However, I am on one to say that the degree of BMM is less capable of taking you to accomplish your dream of becoming a film director.
I shall suggest and share that a specialisation will always be needed. The course of film-making and production or degrees done from institutes like FTII or Whistling Woods or from AAFT or IIMC have the potential to lead you to the aim you are pursuing.
Go ahead and don't stop from doing the course that you are determined to. My advise would be to choose a good institution where film-making is preferred.
