For some stats behind this, the most recent estimate of websites with Google Analytics is around 40 million (1). A rough estimate of the number of websites would be around 1.5 billion (2).
Not sure if you're trying to be intentionally misleading to "win" an argument here, but look at the stats for the top 1M, 100k, and 10k sites if you want to be honest about the portion of actual web traffic Google is able to capture detailed data on.
The fact that "Uncle Joe's Fishing Blog" with a total of 5 hits that weren't crawlers or Uncle Joe doesn't include GA, doesn't really mean much in the context of this discussion. The vast majority of traffic on the web goes to a very small portion of those 1.5B sites.
I was simply providing context for the point. It's also worth pointing out that quite a few of the top 1M, 100k, 10k sites do not use Google Analytics or Facebook.
