I'm currently diving into ethical hacking and learning from platforms like TryHackMe and I'm really enjoying the journey so far. But I’ve been wondering how deep do I actually need to go when it comes to understanding operating systems?

Well I studied an operating system course in the uni that focuses on process and scheduling and stuff like that but I do not feel this is enough for hacking right ?

I get that knowing your way around Linux is pretty essential and I’ve been learning basic commands permissions, and some scripting. But when it comes to the inner workings of operating systems like kernel stuff memory management scheduling, file systems at a low level etc do I really need to go that deep for practical hacking ?
