How do Gas Particles Travel in Straight Lines?

We're studying the kinetic theory of gases in school, and one of the points that was brought up was that: "Gases consist of particles in constant, random motion." How is this possible? Doesn't gravity affect them, or is their mass so small that the effect on their movement is negligible?
