Exactly, when I tell my therapist about the funny things I learned about psychology, it's just me saying stuff that I know now, how I think it's cool, and asking for further information. I'm well aware that he already knows far more on the topic. If you're explaining it with a tone of "you fucking idiot woman, I'm educating you", then that's mansplaining. Another important possibility, is just phrasing a question as a statement for clarification. Think of how a waiter will repeat your order back to you at a restaraunt. I do the same thing when I learn about a new concept. I repeat back what I think I understood about something to make sure I got it right. Tone is very important. If I don't sound like I'm trying to be a dick to you, then I'm probably not.
