Animation re-targeting and procedural animations both use Inverse Kinematics, Don’t be afraid of the math involved, it isn’t as hard as people like to pretend it is.
Look IK in games to see the idea behind it. Interesting fact, IK is also how game characters climb stairs without the feet clipping the ground.
Sorry, I am lost
Can you explain more?

What IK does is calculate how things should act when linked. So if a hand moves to press a button, how should the arm move.
Now any two characters that are the same height,size and bone count can already share animations, Just copy and paste animations in your 3D editor.
Re-targeting is needed for the objects that don’t share these 3 properties.
The way animation re-targeting works is the difference from one characters stance and the second stance is calculated.
This is simple: Rig2Foot.position - Rig1FootPosition = offset between feet.
