The list of topics at the end isn't necessarily "very easy to learn", but I do agree that fundamentals are essential. Depending on the mathematical background of the individual, they may need calculus and general mathematical maturity / ability to solve non-trivial math problems before venturing into the data science field. Also databases. Absolutely need this in the fundamentals, arguably more so than graph algos etc. Edit: English
