Understanding the fundamentals is indeed very important. Not that you need to be an expert in it, but knowing basic concepts is extremely helpful for troubleshooting, and I would argue is the thing that makes the difference between a junior and senior person. I don’t use most of the fundamentals I learned in school directly on a daily basis, but I do use them almost every day to inform the decisions I make about higher level things.
