Not really. There is an element of hard training that incurs risk that is managed by safe training methods.
But there is risk all the same. I don't know fighters who haven't pulled injuries in training.
Well of course, there's injuries in training but smart training hopefully will cut the stupid injuries out or cut the stupid fighters out.
A notable UK UFC fighter a short while before he was due to fight got a case of road rage and smashed a cars windscreen with his fist, he broke his hand, he does have anger issues lol but he had to pull out of his fight because of a 'training injury'.
