Neither good nor bad. I know about microcanonical ensembles, canonical ensembles, and grand canonical ensembles. I have two books where I can look up basics, if some termodynamics notion causes me trouble while working through some paper or book chapter about material more directly relevant to me. From time to time I spend some effort to improve my knowledge of termodynamics, but it has not the highest priority for me either.
Good luck with your question!
