"Well, sort of. There's a difference between learning magic and actually being good at it. Any idiot can make a bargain with a warlock to learn magic. But as for being good at magic, there is a going theory that bloodline makes a difference. Still, someone can just as likely develop immense magical talent right out of the blue."

As Yuya mentions his parents though, Strange shakes his head.

"And no, my parents weren't magical. They managed rental properties."

Which meant that it was a hell of a shock when teenage Strange learned he could actually do magic. There's no hard feelings when he talks about his parents, it's just a statement of fact. They were normal and boring.
