Percentiles

I'm currently 22 weeks & 2days, at our anatomy scan (at 21 weeks 4 days) the ultrasound technician told us our baby boy was at a 60%percentile. So I'm just wondering where everyone else is at, if you know.  I read up on what the percentile means & came to an understanding that it means my baby at his current developing stage is 60% bigger than most babies his age, anyone know if that is even correct? I'm planning to ask my DR but I don't see him for another week.  Thanks in advance ☺️
