That's certainly true, but if someone wants to pursue understanding of these, simply saying "You need more familiarity with ..." gives them nowhere to start, and no terms to search for. Trying to give some context for each item, and to mention some of the underlying words, gives them a place to start, should they choose to spend the time investigating further.
Right, in the next bit I said I just don't think the person asking the question yet has the mathematical tools to tackle either those courses or most of the things you'd get from searching the terms and they'll need to get some more basic stuff out of the way first.
The self-guided search from terms is obviously fine and it's way more than fine to offer to personally give some stranger on the internet pointers as you did.
