If your thumb was attached to the center of your hand, then your middle finger hole would definitely be higher than your ring finger hole. But your thumb is attached to the side of your hand closer to your middle finger than your ring finger. Your middle finger is longer so it offsets some of the greater distance, but for many the distance to the ring finger is still longer.
Try this, lay your hand facing up on the table in front of you. Then measure from the inside crease at the base of your thumb (that's the top of your thumbhole) to the middle of the top knuckle of your middle finger (that's the bottom of your middle finger hole). The measure from the same spot on your thumb to the middle of the top knuckle of your ring finger (that's the bottom of your ring finger hole.
For many, the distance to the ring finger will be a little longer. Thus, their ring finger hole will be further away from their thumbhole than their middle finger hole.
