If you're testing positive for antibodies and negative for the virus RNA itself it means your immune system has been exposed and recovered. This is also what you'd expect to see in someone that has been vaccinated. They would not be contagious at that point because the virus is not present. This is not the same as someone that gets infected but is asymptomatic - they would still test positive for RNA. The percentage of the population that would naturally fall into this group would likely be very small given this is a novel virus so pretty much nobody's immune system had been exposed prior to a few months ago, and we're seeing pretty massive infection rates globally.
