Did I commit a mortal sin?

I was on tik tok in chats and during a battle I went over to the creator and said “this is out of your league” because she had way less points than the other s. She barked back and said some stuff about me but seemed really annoyed and she said it messed with her vibe and I could tell it bothered her. I Istanbul felt so bad and started apologizing and saying sorry she kinda accepted kinda didn’t just asked that I leave chat which I did.

I feel awful about it still now though an hour later I fear I may have dammed my soul I meant it as a joke but clearly it was wrong and a jerk thing to say I knew that and for some reason I still did it. Am I dammned to hell?

I believe this to be a sin because I knowingly went and made a rude comment to someone and even though I may have apologized it still hurt them and that would be a sin right? And it would be mortal because I did so knowing what I was doing and the harm it could do
