What are the chances of the gender being wrong?

I have my 20 week scan at 19 and 4 days on Tuesday. I went somewhere before the covid shut downs at 14 weeks and was told we are having a girl. I’m kinda nervous they are wrong, lol. I’ve already made bows and have a lot of

Girl clothes (handy downs from a friend). It’s totally fine if we are having a boy don’t get me wrong, just curious on the chances. Lol.
