The personal home pages or websites people made using web hosting services like Geosites, Angelfire, etc were mostly a fad of the 90s, and most are offline now. So most of the internet today is commercial web sites, social media, wikipedia, scientific papers, and maybe some blogs. And a lot of this is fake or censored by Google or by the hosts.

Google filters the results to show what is most relevant to your location, or anything else it knows about you (based on the whole profile it build of you about your interests, connections, etc.)

When you enter the URL as https://www.google.com/search?q=pizza&start=1234 (start is the argument that gets increased when you go to next results page), it openly says "Sorry, Google does not serve more than 1000 results for any query.")

It seems that the "About 1.060.000.000 results (0,65 seconds)" is mostly a marketing bluff to give the impression that there are very many results, and Google is very good at finding them. It may mostly be an inside joke at this point. Or at best, a rough statistical estimate of how many pages there may in total be containing the query.

Even if google knows that many pages containing the word "pizza", it would be computationally almost impossible to list and sort them all that fast.
