Theres no "phillips" or "standard" head to it, and its not threaded, so it doesnt screw in, they're punched in, so why doesn't it just come right back out ?

there are several kinds of rivets, but they all work as the previous answerer explained
after the rivet is installed, the down end (the end without a "head" to start with) is expanded to form a "head" that is bigger than the hole it went through
there are several ways to deform the back of a rivet
one way is just to back up the head side and then hammer the "down" side until it flattens out
"pop" rivets pull a central pin backwards toward the upside squashing the down end backwards into a flat "head"

The back of the rivit expands. So the pieces of metal are held together between the head and the rear kind of like a sandwhich

Because it is "bucked" or flattened on the other side.
