ELI5: How can Google give away Google Analytics to so many companies for free and not lose massive amounts of money?

I get that Google owns the data and that is valuable. But, having been in the analytics industry for many years, I also know what Google is doing with GA is very expensive. How the heck do they do it?

Google gives it away mainly because it is an extremely good tool to track your google ads efficiency. By being free, GA is used by almost 100% of website owners, who can then easily track google ads results and ROI. That way, they are a little more inclined to invest in Google Ads, which generates around 10 billion dollars revenue a month for Google.
