Anybody have a ramzi theory read and it be wrong?

I had a trans vaginal ultrasound done and then I wanted to do something fun cuz with my other three pregnancies I never heard of the ramzi theory, well I sent my ultrasound to a lady and she said it’s a girl and I really wanted a boy lol I have one boy one girl and my angel baby. Anyone’s ramzi theory be wrong? I don’t understand this stuff google says left side placenta is boy and right side placenta is girl unless it’s a trans vaginal ultrasound then it’s flipped but idk lol
