The entire gravitational field of all of the mass of the Earth is pulling down on that little ball, and your arm is able to toss it in the air, even though you are much tinier than the Earth. That's because your arm's forces come from electrochemical reactions, which are enormously stronger than gravity on a particle-by-particle basis.
