With the free and open source software application, Blender 3D (available from the Blender foundation at: https://www.blender.org/ ) the possibilities are endless.
Rendering. Modeling. Sculpting. Animation and Rigging. Story telling. VFX. Simulation. Video Editing. Scripting… I mean where do you start? There is almost too much to choose from.
For anyone who is a newbie and is simply curious, I suggest looking at ‘Blender Hut’: https://www.blenderhut.com/ . This is how I started. It was daunting but ‘tutor4u’ made it manageable. Whilst I may not be in a position to creating a block buster movie, I am quite chuffed I created ‘Tony’.
