There are no "major topics" in man, it is a database. you enter "man command" and it tells you about the command. Try it with some of the commands you know. You can even enter "man man" to get help about "man".
There is also a keyword search, "man -k keyword" (or "apropos keyword", which is the same), which will bring up a list of articles in which "keyword" is used.
The only major grouping is that the man database is grouped in "sections".
I suggest you start with "man man", the sections and their contents are laid out there. Unix expertise is not so much about knowing everything, but to know where to find everything. We all use "man" frequently, many times a day, to look up certain information. So you can't start early enough to develop the same habit.
I hope this helps.

Used to find the location of the whatis database files. See manpath(1) for additional information.
PAGER Program used to display files. If unset, more -s is used.
