Explained being nonbinary to a cis guy, here’s how it went

So I am in middle school and corrected a teacher on my pronouns. The next day, some guy came up to me and asked about it. It went something like "Don't get mad at me, but are you, like, trans?"

Ofc I said yes, and said I was specifically nonbinary. He asked me to explain, so I held my fingers out like 🫵 🫵 and said "This is masculine gender and feminine gender. Most people are somewhere on this line." Then I moved one of my fingers to the center and then up and said "I'm over here; outside the binary."

Did I explain it right?
