Are some parts unnecessary and how can I identify them?

Hello everyone. I spent a few months slowly relearning trig on Khan academy and near the end found the things it was teaching to be so obscure and niche that I couldn't imagine what kind of practical application they would have. Obviously, I am sure some field of science must use those, but I can’t imagine it’s worth everyone learning. I assume the Pareto principal must also apply to math and I am wondering how I can Identify the most useful parts of any field in math. That’s not to say I only want to learn 20%, but I would definitely like to avoid the 20% that is extremely esoteric and unlikely to ever be useful for me. Currently, I am learning pre-calc; any suggestions? Thanks!

I suppose one way is to take a first guess at what you think you can ignore and ignore it and continue on with your coursework.

If at some point you find you were mistaken, and you do need that info to continue you can always go back to it.

If Khan academy really has 20% useless info, well shame on them. I do find that number a bit hard to believe.
