Adobe Creative Suite or Unity / U4E

Guys, I am mostly on social media for V/FX and am keen to learn some new skills directly in animation. Now with real time CG created by Unity, for example, I am wondering if new learners should even bother to learn ACC like PSD, AE , Illustrator? Can members here fill me in with the pros and cons and why not just game engines to do all the original art, 3D, animations or even animated films and what would be the need to learn PSD or AE? Thanks.
