Most brake pads have a little piece of metal that rubs on the rotor to make the squealing noise while you still have a small amount of pad left. If your pads don’t have this, it’s the metal backing off the pad rubbing on the rotor.
If you live somewhere that sands the roads, you can get sand, or debris, between the odds and rotors that make the same noise.
The material they make brakes out of today is specifically made not to squeak. They put a lot of money into research to make sure of that.
They also add a little metal clip that will make that squeak when your brakes are almost worn away. Without that, the first squeak would mean that you were clear through your brake pads, and you’d have trouble stopping. The clip should give you enough warning so you get them replaced before they can cause problems.
