Eli5 – how does the new google phone know what’s behind the images it removes from pictures?

Question

I keep seeing these comerciales for this new google(?) phones that will remove background images in photos (like people and animals). How does the phone know what’s behind the images that are being removed? Have they just photographed every inch of the earth already?

No, it just infills with a pattern that matches what’s at the edges. This means the result will be entirely fabricated and not match reality.
