Getting Started with the Unity Animator
The Animator component is a powerful tool but it's a little confusing.
In this video I use Kenney's amazing 3d Character asset (get them here):

We go over importing them, setting up humanoid animations so we can re-target any animation to our model and how to create and code transitions between animations.
This is aimed at the beginner, but implementing this into your own characters is still going to be a challenge. Hopefully this will be enough to get you started.
