Navigation and routes vs. pages

I’m pretty new to Statamic and need to get the feel for it just yet. I’ve searched the internet for my problem but couldn’t find any answer (not even in the documentation), so here I am:

How would I add a navigation item to a page that is generated via a route? Do I have to create an empty, non-functional page for that in the admin area? And am I interpreting this correctly that routes are overriding page slugs if they are the same?
