If that's the case then they're prioritising kids. Which is what you want.
For me, that's the weak link in the system, new, younger fans, which is how we increased the fan base last time we were here.
I'm not really bothered about adults who didn't even amass 500 points last season, let alone in the years before then.
The other problem however is that with so many season ticket holders, even if kids tickets were made available now, it's unlikely that there would be a seat next to their parent anyway.
