I'm still a beginner in mentalism but I don't believe you need to read 13 Steps or even Fundamentals to get past being a beginner same goes with Royal Road. There are plenty of other books and videos that can go over similar material that can help you understand more about mentalism.
However if you are buying effect after effect then you certainly are a beginner and will stay that way until you get a book or video dedicated more to teaching presentation rather than effects.
13 steps to Mentalism
Fundamentals
Newest one I have been recommended is Alchemical Tools and pratically the best thing in mentalism from many reviews from top mentalists and smaller practicioners.
