If witchcraft is real is magic real too?

I would say yes. But then I have been a pagan and have practiced various forms of folk magic since I was in my teens. I got into this just before the original movie The Craft hit theatres so that should tell you how long ago that was.

And I would not have stuck with something for decades if there were no results.

Lol If magic were real then the universe would have absolutely no order. No physical laws. As magic would continually violate any natural law into irrelevance.

Anything is possible within our vast Universe.
