It sounds like what you are really asking is about filmmaking and how different are the two styles of filmmaking from each other. And it is absolutely true that they share some similarities in terms of portions of the business. Both require planning, writing, storyboarding, scripts, and actors. You may even find overlap in much of the equipment you use. And it is possible to tell the same kind of stories in both media. The advent of modern effects and CGI has further blurred the line between the two. But many of the nuances of the storytelling and styles of story you choose to tell will be affected by the media you choose. And there will be obvious differences. Your actors will be chosen for the vocal talent in animation and you will need good artists and people with experience in animation lighting. You may need camera work depending on the style of animation or you may need computer work. In live action filmmaking you you need practical and visual lighting effects people and your actors will largely have to look their parts. Learning how to do one will give you a head start on someone who is untrained in either, but both take time to master.
So after doing some personal research and using my previous knowledge, though animation and filming are similar, they are not the exact same. Animation is typically seen in cartoon styled movies and are made from drawings and other graphic designs. Filming is typically using a video camera and recording real life objects such as people, places, or things. Though they are similar because they both play large rolls in the film industry, they still have their own distinct traits. I hope this answer helps!!
