The list is for beginners.Ofcourse data science is a huge domain and you can't actually make a roadmap to be a master in this field but I am sure this list will help people to get basic understanding of what to read and how to workout things.
I think the list is more helpful for someone a step or two beyond beginner. A true beginner is going to look at that and be scared. Once they've read a few introductory things, they'll be able to go back and make better sense of it, for sure. (I showed this to a friend of mine who's interested in learning data science and that was his reaction, so I am generalising, but I think it's a fair generalisation.)
