FRICTION.
Gravity only holds the ball to the floor. The ball has rolling friction which is really just the action of flexing while rolling. That's why really hard wheels roll a long distance compared to "soft" wheels.
Also, the air is providing friction resistence. That's how curve balls are pitched.... so yeah, air has friction too.

If the ball had been rolling in a vacuum, such as in space, then it would just continue moving. In a normal environment, however, there are forces acting opposite to the ball's motion, causing it to eventually come to a stop.
