I agree that it's very poorly written. The heading is especially confusing, it took me a long time to understand that "SerpAPI" was the search term, not a Google service. It is also the name of the company he's promoting, which makes it even more confusing.

But I don't agree that it's "obvious" that "you're not going to be able to browse to page 187,398,384 to get those results. I would argue that a search result is only a search result if you can actually view it. If not, it's just a marketing, or statistics.
