Buy motion presets for Animate cc?

I use Final Cut too, and am doing a lot of things that I can't imagine being done in Animate.

There are a few things in those videos that, as Thomas pointed out, make it seem likely it was After Effects. Mainly the 3D animations and the motion blur. Most of the basic movement could be done in Animate.

There is a Motion Presets window you could look at. Try selecting a shape on the stage, pick one of the presets and click Apply. In the timeline you'll then see that your shape has a 15 frame span, and scrubbing the timeline will show that it's animating in the way the preset suggested it would.

If you now double-click on the gap in the timeline between the two key frames you will see how the motion tween is achieving the effect. You can also move the curves or add different easing. It's not an easy display to look at, hopefully you'll make some sense of it.

Character animators I know tend to do frame by frame animation to give their characters life, and generally don't use motion presets.

Also look for videos like this one that take you through what you do with the motion editor:
