Technician said she could take a good guess at baby's gender

I'm 19 weeks and dying to know what I'm having. When I had an ultrasound at 11 weeks 4 days, the technician asked if I wanted to know the gender because she could take a good guess (but said it wouldn't be for sure, just her educated guess).

Do you think since she could take a guess that early, it means boy since there's more to see? Or she's just better at identifying a nub angle and it could be either? I hope this all made sense haha. I just feel like it's a boy now since she could guessed that early on.
