Baby is breech at 20 weeks scan

Amy • Mom to 4 beautiful girls. 3/3/10, 4/27/14, 4/8/17, 3/7/19.
I know that's completely normal for that time frame and baby has time to flip. What I'm curious about though is that I heard when given what "gender" baby is in breech position it's easier for the tech to be wrong? Is that true?
