So we aren't restricted to the magicstyles we start with?

Nope

Its just hard to learn new magic style, depending on what you start with. 

For example, a guy with physical buff would have an easier time learning healing (as they are both focused on the human body) than elemental magic. And its not just magic that effects how easily you learn different types of magic. Your character could learn physical buff more easily than, say conjuration because he knows how to box.
