Lola was at the top of her class at St. Tabularasa's, and the prof said Randolph could amount to much more as well if he put his mind to it. Obviously, they both did well.
Generics don't age, but characters in books do if they age in the course of their plots (or backstories). Also, generics may not necessarily come out of school at exactly the age they are going to be in their books: do you remember Miss. Havisham telling Thurs that she had originally aspired to play young Estella?
Another possiblity is that Lola left the well to spend time in the Outland - "Lola Vavoom" does have quite a solid career there - before returning to the Nursery Crime series. The only problem is that I think JFf mentioned at some point that fictional characters don't age in the Outland. It would make for an interesting casuality loop, though: Lola (Ibb) in WoLP imprinted on Outland Lola, which made her the character she became, who she later imprinted on, etc. ...
Metaphors be with you!
