Talent or no, people are able to choose their profession and specialization. Paul wanted Rudeus to follow in his footsteps, but he didn't, he went down the mage route instead. Eris was supposed to learn magic and basic education to become more civilized and not a misbehaved brat, but she never got good at math or magic, and became far more interested in sword fighting techniques. Zanoba has no talent in earth magic but wants to learn anyway, and then ultimately study the doll mechanisms and notices enough that he can clue the others in to help Nanahoshi make her breakthrough.
Aisha is free to not focus on any specialization and just become a housekeeper.
