I suggest you to before jumping to the 3D animation learn 2D animation. I use Photoshop, which is available in Windows and Mac, but there's also Clip Studio Paint; The animator Kamuo makes his animations with that software if you're looking for references. Also, for 3D animation, I suggest you Blender. Blender have some high quantity of references and tutorials too, and most of them are, in my opinion, better done than the Daz tutorials. Also, using Blender you'll get used to the UI and to the keyboard commands, which will be a key part of learning animation in Blender.
Now, if you have a good PC and want even more tools than Blender, consider using Autodesk Maya, but learn Blender first because is easier than Autodesk Maya. Also, I have understood Blender is free, while Autodesk Maya costs $450 per three years. If you are interested in using Autodesk Maya, then first learn Blender, principally because the tools are more complex, so it's not a good idea for a novice. Not so much animators use this software, so you'll have less references.
