They do host them on their servers, sort of (if you’re asking how ad brokers work that’s a bit of a different scope).
Does poo have to be on your desk to smell it? The post office (website) is telling you (your computer) to go over and pick up a parcel of poo that’s there for you. You say no, I don’t think I will (adblock/poo block)

Some do. YouTube switched their ad service so the main video and ads come from the same server. To get around this uBlock now blocks the script on the browser side that shows the ad, then returns a signal that the timer is up.
It’s a constant game of cat and mouse to get around ad blockers then block that new method.

I don’t think the new strategy of injecting ads directly into the video stream can be defeated in realtime though. It’s like how you cannot defeat tv ads…you can blank the screen, or record and restitch without the ads, but the content itself has the ad. YouTube is a bit different where you can theoretically skip ahead, but your device has to tell Youtube that it wants to skip ahead in order to actually even get the video content, and youtube can look at request timestamps to know you didn’t see the whole injected ad and just re-inject it in the video stream.
