I agree with you.
Disc golf is, by and large, a very amiable sport. I've been in your shoes (albeit with smaller prizes and bragging rights at stake) and have said similar things. I don't think it's bad form at all. I think it was just you trying to form a bond (however superficial) with your card-mate. Interaction breeds more familiarity, familiarity breeds friendship, and friendship breeds more fun. Unfortunately, this cat seems to want to scapegoat your factual statement to his self-destruction. That's a shame.
People much wiser in the sport than me have said "it's bad form" and/or have related stories (however anecdotal) how top pros never discuss the score. Point taken, but the fact remains you were playing in the amateur division. Nobody can legitimately fault another person for their poor play unless their opponent physically interfered with their throw(s), especially amateurs. If your game $hit the bed after someone told you the score, then you need to work on your mental game and quit looking to blame someone else for your missteps.
In short, there's always something or someone to blame your bad shots on if you look hard enough, but those fragile egos who do are typically the same people who do that in other aspects of their lives as well so no amount of contrition is going to absolve your perceived "sin" anyway. Don't sweat it; it's his problem, not yours.
We're throwing frisbees in the woods, bro. It's not that serious.
