Why calculate velocity to get odometry ?

Hello all , I'm new to ROS and was trying to publish odometry data. What I don't understand is why do I need to get the "velocity" of the robot to get it's current position ? Couldn't I find the position of the robot right away from the : total encoder ticks & ticks for each meter(const to my robot) ?
