Yea you're completely correct, any computer science degree worth it's salt will cover computer architecture, networks, basic maths, etc. Do I remember every little detail about how transistors,the memory bus, or every network topology works? nah of course not, but does having a reasonable overview of how it all works under hood help inform system design when you're tackling the hard problems, performance, reliability, security,etc? Knowledge is power, so more knowledge can never be a bad thing.
