Much more likely is that it is simply condensation from the person's hot humid breath onto cold metal contacts, which would mean it is pretty clean water. Granted, if you are coughing into your games or otherwise incapable of blowing without adding a bunch of phlegm, then a little something extra is being added to the mix!
