Most things are not hard if you spend the time and effort to learn. I recommend Francois Chollet's book on AI. It has good reviews so it will help you learn the tools, techniques, and concepts in AI and ML.
If you can't afford to buy the book then there are online libraries like Anna's archive which should help you get a copy and then buy the book once you have a job and can afford to spend money on books.
