In Google Analytics real-time visitors, how does Google determine if a user is a mobile, tablet or desktop user? By resolution of the device? By browser headers (seems unlikely because I believe it's hard to differentiate different headers) or some way else?

I believe GA uses the user agent info to identify the device (whether it's real time or not).
Run the following in your console, and you'll see the data:
navigator.userAgent
