No, Google's business is using your information as a tool to build products it sells to third parties. Actually selling your information, as such, would undermine that business.
Google business is no more about selling your information to other people than a ferryman’s business is selling his boat.
Your privacy against non-Google actors is Google's moat. They have every interest in protecting it.
Really? If we're going to be that pedantic, then it's probably more like " Google's business is using your information to build products it sells to third parties." They're not using my information as a tool, they're using my information (location, interests, browsing habits, searches) to sell a product (advertising). At that stage, they _are_ selling my data.
Google's business _is_ selling my information to third parties. Don't Apple have a better track record, and a more privacy oriented business model here?
