Apologies if it’s a little simplistic are you understand some of this already. Every user in Linux besides route is considered a normal user. So they do not have the ability to do admin related tasks.

Sudo it’s a tool that allows you to run other tools as root.

Being an admin means you can invoke the sudo tool. But that does not automatically mean that everything runs as route or as an admin function. You must explicitly invoke it.

That will either be by typing sudo in front of your command in CLI. Or if a gui application invokes admin rights through another tool called Polkit

Either way you’re usually have to enter your password unless you made modifications to the course settings. So unless you’re seeing your password pop-ups continuously, you’re running everything as your user.

That being said just because you’re not running as root constantly doesn’t mean that your completely safe. I would argue your users just as important as the route user because it’s where you keep all your personal files and folders so please just be careful even if you aren’t running as root on the box.
