Unlikely gps at that price, but maybe? Likely just cell tower based location.

GPS chips cost cents. Before I shared news from 2007 where GPS chips had a price of $5.

What does this mean? These don't work?

Not sure. But getting a gps fix with no assist, tiny antenna, and not much computing power doesn't sound plausible.

I never got a working gps fix with cheap Chinese Android phones even. Only high end ones.

This is unrelated to the chips and has more to do with bad design (the biggest factor in GPS). Computing power needed is trivial as well.

Now I'm curious how cheap GPS receivers work, since I'm only (somewhat) familiar with the workings of high-precision stuff.

GPS receivers are very simple and not "high-precision". It's very simple math. Inaccuracy was artificially introduced.

We're clearly not on the same page here.

I'm not talking about artificial inaccuracy but difficulties like very low SNR, need for many correlators for reasonably quick fix, etc.
