Every object in existence, regardles of how big or small, exerts a gravitational pull: however, I am assuming that halo's gravitational pull (keeping you and the atmosphere on-baord) is caused by centrifuge as the ring spins, and thus, should you step over the side of the rings barriers, you would... well, float away, i presume.
