Where to start?

Hi, I am a developer and have always been interested in ML and especially in RL. I finally want to start learning. I have a basic understanding of ML and training.

From my understanding, I should start with revising basic maths and trying some basic coding projects to start with before going deep. Please suggest what I should cover and any courses that I can look at. Deep Reinforcement Learning Course by Huggingface seems interesting.

I am not asking for zero-to-hero steps in a month (I know that’s impossible); I am willing to spend time daily and give it a genuine try.

All the suggestions, advice and personal exprience is welcomed. Thanks in advance.
