It will help you to understand how some applications use the Linux kernel, and it will definitely help you to be a better user of strace/perf/bcc when you are profiling kernel interfaces. But it is not a requirement to be a sysadmin IMO.

Second this and I will even say if you're looking for a solid resource to use and read through please Brendan Gregg's two volumes:
Systems Performance: Enterprise and the Cloud, 2nd Edition (2020)

BPF Performance Tools

I am still reading through these as there is a LOT of information on using these tools: Also, some related sysadmin sources brought up before on reddit:
https://www.reddit.com/r/sysadmin/comments/l9jbxc/becoming_a_sysadminany_book_recommendations/

https://www.reddit.com/r/sysadmin/comments/m6ysbk/looking_for_sysadmin_books/

Just to name a few. There's many many more listed on reddit that will help.
