On a given Google search, you have one to four ads, maybe an AMP carousel, and a knowledge graph box. Somewhere is the end of what fits on your device screen. Past that is the first real search result.
Google is making money because everyone thinks the first ad is the first search result (They're nearly indistinguishable, visually, and studies have demonstrated non-technical users can't tell them apart) and then everything below the ads that fits on screen is packed with links to other Google properties.
We are at the point where organic search results are nearly the "page three" of Google Search: Somewhere nobody goes anymore.
