No, you do not need a drawing background to be a 3D animator. That being said, you can learn a lot from drawing that will help you in your animation. When you are doing life drawing you are taught to look for lines of action, strong silhouette, balance and weight.
These are all things that animators use daily when posing out their characters for their shots. Being a student of a different art form besides animation, such as drawing - acting - photography, will help you grow into a well rounded artist that can only help you in your animation.
