Where to start learning?

Found out about Jetson courses in a youtube video.
I’d love to start learning Ai.
But am a bit confused where to start.

I know Python (not expert). I’ve completed a bootcamp in Data Analytics and have done some machine learning.

I’d love to learn Ai to control robots and drones. I saw a video about hands on with hardware - that looks really interesting.

Hoping someone can suggest best places to start.

Thanks.

Someone else might mention the CUDA and other learning URLs. This is more about the platform itself:
