Yes it it true. The reason why is because of a projectile's definition states that the only force that acts on it is gravity. Since gravity only affects the Y directions, the X direction dose not change and remains constant. But this is only true for projectiles, a ball thrown up into the air in real life is not a projectile because of the external forces acting on it other than gravity.
