I work in a small helpdesk team and handle a bit of everything. I can fix some recurring issues, but often don't understand how the pieces connect. For example, I can set up a mapped drive without really knowing what happens at login, and DNS still feels fuzzy.
How do you build that bigger-picture understanding without feeling overwhelmed by everything you don't know?
Pick one thing that keeps coming up at work and follow it through, rather than trying to learn all of networking at once. Start with a high-level explanation, write down the questions it raises, then dig into those one by one.
DNS is a good example. A computer asks a DNS resolver for a name, and the resolver may answer from its cache or query other DNS servers. The computer can also keep a local cache, which is why flushing DNS locally can help even though DNS servers are elsewhere. Try looking at a few queries and results on a test machine as you learn.
For the mapped drive, try tracing the login process in your own environment. The folder itself is usually on a file server, while the drive letter is a connection the client presents to the user. Active Directory can store a home folder path, and Group Policy can also be used to map drives.
From there, look at authentication, how the client finds the server, and how SMB provides access to the share. Check which method your company uses rather than assuming every mapped drive works the same way. A lab is a good place to experiment without breaking someone's access.
If the gaps feel too scattered, a structured fundamentals course might help more than chasing random topics. A+ and Network+ study courses or textbooks can give you a sequence to follow. You don't have to take the exams unless the certifications are useful to you.
Not knowing the mechanics behind every fix doesn't make you bad at helpdesk. There's a difference between knowing a procedure and understanding the system, and both are useful. Keep a short note when you use a fix you don't understand, then revisit it when you have time instead of judging yourself in the middle of a ticket.

And ask a teammate to walk through the why when there's time. A quick explanation of your actual setup can make the reading much easier to connect.
There is simply too much computing for one person to know it all. People come into IT with different backgrounds and develop different specialties, so comparing your gaps to someone else's strengths is a rough way to measure yourself. Follow the areas that interest you and build depth over time.

Also worth checking your workplace documentation. Knowing the general flow helps, but the actual DNS configuration can differ between environments.
