>one reason it works so well is because it is a very strong signal that the applicant has resources that a random strong applicant doesn't have.
When I was a university student, I accidentally established my own network just by getting involved in my department as a TA and undergrad researcher. My department would openly advertise those opportunities, and I was shocked at how few of my peers took them up on it. This involvement revealed opportunities that were really only disseminated within this TA/research community. While technically anyone could have applied to those internships and jobs, you'd be hard-pressed to even know about them if you weren't involved in this community to begin with. At that point, I "beat" the competition by playing somewhere where there's a lot less of it. It's not about being any "better" than the competition, but by strategically avoiding it.
This is how real networking looks like, and how someone (in my case, a lowly student) with little established experience and history can do it. The particulars can vary from one person and environment to another, but the trick is to start small and follow the unique opportunities presented to you.
