My understanding is that is identifying as male, right? No one identifies with all of the characteristics of whatever gender they are part of. If you identify yourself as a man and are afab then that’d be trans. It doesn’t matter how strongly you identify as a man.

I’m not sure why your 100% thing is there except to try to wiggle out of being wrong. No one is 100% of a gender, because you literally can’t be a perfect archetype of a gender.
