It means, simply put, your engine, emission controls & catalytic converter are working really well.
To simplify:
CO is directly related to fuel/air mixture, HC readings ( if high ) usually indicate ignition or oil-burning problems, NOX is directly related to the EGR ( exhaust gas recirculation ) valve on an engine.
As I said above, these are as close as I can come to translating your readings into layman's terms.
