<Snipped quote by Three>

The use of the word "merely" makes me feel like you misunderstand what constitute's as "age appropriate" in this universe's context.

Not really? Even considering the nature of the world, the younger someone is the more important a gap in experience can be. The gap between someone who's been training for a handful years/hasn't ever had to fight for her life because of coddling parents and someone who's been training for only a couple of years moreso is going to be much more than the same couple of years' gap when the two have been training for several decades. She's competent and was deemed solid enough to be sent an offer letter, but when push comes to shove she just doesn't have much real combat experience that's not from sparring.
