Maybe in mechanics (the Belmonts don't usually cast magic unless one of their mommas is a Belnades) but again, going back as far as Leon, they have a magical bloodline. They are Skywalkers, Potters, etc. They get the free destiny and power suite to go along with it.
And hey, I'm perfectly fine with giving every PC fighter a bloodline and destiny as part of the kit. I've been perfectly willing to make every PC fighter a chosen one hero/villain imbued with supernatural power. Make them all Percy Jackson. Let completely normal run of the mill warriors be NPCs. Every PC class should be special by default. Everyone wants to be Superman, not Jimmy Olsen. The amount of mundane options in 5e fills a thimble with room to spare. Get rid of that and you add so much more design space to work with.
