Hubbard spoke to Kiwi fans who gathered at New Zealand house — aka the QT Hotel — the day after competition.
She deadpanned that the medical team had diagnosed her arm as "busted", which drew wry laughter from the audience.
"It looks like it will be a career-ending injury, which is a real shame, but I'm glad I've gone out trying to achieve my best on the platform because, as the [New Zealand team] slogan says, 'you have to earn the fern'."
Hubbard's case as a transgender athlete who had previously competed as a male generated debate ahead of the Games.
Post-competition, she was asked if she had been treated with respect and inclusivity at the event, whose mantra was "humanity, equality, destiny".
"Without any doubt I can say that's exactly what they have done.
"The Commonwealth Games are a model for what sport can and should be. It's an incredible environment and an amazing atmosphere."
Hubbard claimed New Zealand's first medals at a weightlifting world championships with silvers in the snatch and combined at Anaheim in December.
The International Weightlifting Federation worked within the International Olympic Committee rules in which she was eligible.
She had to demonstrate her testosterone levels were below a certain threshold for 12 months before competing for New Zealand.
