The concepts are not individually hard, but they build on each-other (sometimes unnecessarily, but sometimes very helpfully). If you care about understanding the tools you should take the few years of study it takes to learn the notation to a level of fluency, or you won’t be able to read the vast literature written in that notation.

It’s like if you’re interested in 19th century piano music, but all your experience with reading music is in the form of guitar tablature, then you’re going to have a tough time with your study. You could conceivably find top-down videos of someone playing some of the music you care about, or convince someone to translate some parts of it into guitar tablature. But it would be a better use of your time to just learn to read standard music notation.
