We had a kid who was 9 or 10 on our pair. I have seen plenty of little kids bowling in them. As long as they can bowl the 3 games and the Jr. entry fee is paid, they can bowl.
The 13 or older is about receiving information from them if you provide an email address. It doesn't seem to relate the actual bowling in the ProAM.
