There’s good evidence humanity was down to the tens of thousands before, yet here we are. Source. I’m not saying we’re guaranteed to get through it if it happened again, but a drop to half a billion people wouldn’t even necessarily cause a significant reduction of genetic diversity.
If an event like this happened, we could easily maintain most of the trappings of civilization with a little effort and cooperation. So yeah, you’re probably right.
Cynicism aside, civilisation as it is today requires extremely specialised knowledge. Losing 95% or more of our population would put an end to our capability to support any kind of advanced infrastructure. It’d be akin to the decline of Rome, from the biggest city in the world to having farmers farming in the former city area and mining the old buildings for building material. Humanity would be back to scavenging and farming as core activities within a generation.

Fair. Less the extinction of humanity and more the end of any trace of civilisation
