How to us ML for trading - Beginner

Hi There, my first post in here. I have been a trader for 18 years, and I was curious on using ML or AI for trading. I have done a course recently on AI from Oxford University.
The idea was to implement AI in my trading.
I am going through many YouTube videos , etc. but I am totally lost where to start and how to implement this.
Any experts in here could help me it would be much appreciated. I am really passionate on this. Thanks Paitech
