Honestly, every skill is necessary for a career in the film industry. As stated previously, the best advice anyone can give you is to learn both! Based on what it is you want to do, you will decide the career path that best sparks your interest or reflects your skills. Research people who currently are in those roles and see if you can relate!
These terms are more broad, but I'm gonna keep it simple, but honestly they are two different things.
Cinematography is the photography of moving images. It is the art of determining the composition of a scene during production through lighting, color, placement of the actors in the shot, etc. and the best effect you envision for the film.
Editing is the process of selecting and mixing the film in a sequence conceptualize the film with special effects. You are able to figure out how to capture those "moments" and evoke those emotions based off how long you stay on or switch back and forth to a frame.
Both appeal to the artistic vision, but cinematography is more so the visual concept and editing is the process.
