There are many arenas to sound concerning film and television. They do not all involve being on set and owning "gear". Listen to what JonG said above, get out there and see what sound positions you land out of school. If people ask you to do production sound for a project, remember what your favorite gear is to use and then locate a place to rent it. If they ask what you own, just say you own it, then charge for the rental. If this helps, even the best pro sound mixers do not own all of the gear they use for a full fledged production.
