Those are all very different professions... Realistically you should choose the one you are most interested - the earlier you start pursuing it, the more time you have to become really good at it. To be a video game designer, you'd have to have a lot of experience in computing and writing codes (very technical stuff, very difficult), and a similar experience for becoming an animator. For becoming a voice actor, look up videos of 'behind the scenes' for your favourite shows or video games to see real voice actors in actions. You want to have a full idea of what each profession entails before you make any choices - regardless, I guarantee that in a few years you'll want to be something completely different!
