Looking at the Statcounter report, it explicitly excludes mobile devices and separates out ChromeOS. I'm guessing that Statcounter uses UA strings and it is conceivable that HTTP requests are happening outside of explicit web browsing.
Their data source is the analytics JavaScript that webmasters install on their sites. Non-browsing HTTP requests are unlikely to target pages with those scripts installed, and even less likely to download and run them.
