galaxy : any of the very large groups of stars and associated matter that are found throughout the universe — Webster
Galaxy is a massive, gravitationally bound system that consists of stars and stellar remnants, an interstellar medium of gas and dust, and an important but poorly understood component tentatively dubbed dark matter. Galaxies contain varying amounts of star systems, star clusters and types of interstellar clouds. In between these objects is a sparse interstellar medium of gas, dust, and cosmic rays. Dark matter appears to account for around 90% of the mass of most galaxies. — Wikipedia

"He [God] does not play dice," quipped Albert Einstein, but for mortals chance is part of life. We cannot experience, measure and predict with absolute certainty. We may win a prize in a Christmas raffle. There's also a small but real chance of being struck by lightning.
