I think you should ask a moderator or staff.
I am afraid I might get banned because of this game

If you have not cheated you have nothing to worry about. People do not get banned just because they've been reported. If that was the case, this site would be a very empty place.

I took a Chessly course by GothamChess on the Vienna, and I played the right lines and got a great position. In fact, my opponent resigned after the 13th move.
However, it says I played a perfect game. I am concerned I might get reported or something.
Can somebody give me clarification on the situation?
Your fine, once for some reason my screen was like hacked and I would auto resign even though I didn't do anything, chess.com didn't ban me for sandbagging so you should be fine in this case.

Great game for you. Also, did you get castle victory from that game?
if u checkmate when castle, its a castle victory. Ex: in the Emanuel Lasker game where he sacs the queen if he O-O-O# then thats the castle victory
