No, it's not, someone is simply rude and talks over everyone. A rude person will talk over men, women (without being sexist), black people (without being racist), etc.
Either you demonstrate that the arrogance is specifically targeted towards women and because they are women, or you cannot speak of sexism.
When you defer to men and interrupt women, it's sexist. They were talking amongst themselves and ignoring the woman there, who happened to have actually spoken with the player.
