No. Sorcery is science.
Magic draws on 3 things: physical skill, unknown science, and faith.
Some people are very quick and nimble, they can swipe your watch and pop balls under cups without you noticing.
Faith comes in because people want to believe. Our minds take the simplest route of explaination.
Science plays a roll because if you know a scientific fact that others do not you can use that to show something new to an audience and because they haven't worked out the details. Think of the fun you could have with magnets if your audience didn't know you were using them, or didn't know how they worked.
