I am not the Lazy programmer nor the owner of this website, but titular Lazy Programmer has developed several roadmaps of the courses they offer for those who wish to learn AI/ML. You don't necessarily have to take their courses, but you can glean the topics of the courses from their titles and get a good idea of what you need to know.
The courses:
