There is a tolerance for error that is allowed in the interests of saving costs during manufacturing. The second factor is consistency of density. A billiard ball with a consistent density rolls true and straight.
The weight of the ball is evenly distributed allowing the ball to roll evenly no matter where cue strikes it. Billiard balls with an inconsistent density play erratically. They zigzag while rolling at times because the weight is unevenly distributed.
