I can't help but ask... How much risk is "little risk" here? Can they still contribute to the spread? And what percentage of population can fall into this group

  We don't know. The period of immunity following infections varies, and this virus is not well understood.

  I think if you test positive with an antibody test but not an rna test it means your immune system has the ability to fight it off from a previous infection but the virus isn’t currently multiplying inside you.

  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.
