Because a talented person can throw it so that its' spin is effected by the air and changes it direction.
.
The surface of the ball is not smooth. The pores of the leather and the sewing of the thread gives the ball a non-uniform aerodynamic surface.
By causing the ball to spin forward relative to the flight of travel, the ball will create a lower pressure zone above the ball and the ball will rise up at the expense of losing energy more quickly.
By causing the ball to spin in other directions relative to the path of flight the ball will fly accordingly.
The threading adds certain qualities to the aerodynamics that can be used by the pitcher to accentuate certain behaviors.

What make a curve ball curve when you throw it?

What causes a soccer ball to curve when kicked?
When a soccer ball is kicked, the spin applied to the ball causes it to curve in the air. This is known as the Magnus effect, where the spin creates a difference in air pressure around the ball, causing it to curve in the direction of the spin.
How can you effectively curve a cue ball in billiards?
To effectively curve a cue ball in billiards, you can use English, which is a technique where you hit the cue ball off-center to make it spin. This spin will cause the cue ball to curve or change direction after hitting another ball. The amount of spin and the angle of contact with the cue ball will determine the curve. Practice and experimentation are key to mastering this skill.
