I would wager that some people are gifted and are a source of magic themselves, so they become magicians. Seika on the other hand does not have any magic of his own, but is capable of using the ambient magic. From his father's knowledge, there are instances of people using magic despite not having magic of their own, but they cannot become magicians. So there is a gap between those with and without magic that cannot be bridged by training.
Still, it's odd that he wasn't more curious about his son's feat. After all, Seika has clearly not been educated in magic, as he had to ask his father about whether he could become a magician despite not having any magic, so he lacks knowledge to that extent.
