Learning is an essential part of being human :D I definitely still have more to learn either way.

It's important to note that some NB people do consider themselves trans and some don't... Which can get a bit confusing if you're out of the space itself.

I just personally worry that any sort of blanket classification of NB people as non-trans can lead to the erasure that bisexual people experience. (Bisexual people are often called "gay but trying to hide it" even within LGBTQ+ spaces)
