Players jumping up because they never got settled and confidence with their stance, balance, stroke, or aiming, etc for the shot and were already lacking confidence as a result and anticipating missing? Happens regularly.
Players jumping up on shots they were intimidated by and had no confidence in? Happens constantly.
Players jumping up on shots when feeling more pressure because of the situation like maybe it is a game winning shot or other do or die situation? Happens constantly.

Players who suffer from some kind of pain or discomfort such as arthritis or back pain while in their shooting stance which causes them to jump up often as a subconscious reaction to wanting to get away from that stance pain asap? Happens a decent amount with those afflicted but the number of afflicted is relatively small.
Players who jump up on most shots as a matter of habit? Depending on how you want to define "most shots" there are a pretty decent amount of these players out there.
Players jumping up on the shot because they can already tell they missed the ball before it gets there? It happens, but not all that often in comparison to other causes. And you usually aren't going to be able to react that quickly either unless you were already anticipating the miss as well. Maybe you were already anticipating the miss due to the pressure, or your lack of confidence, which may or may not in turn have also caused you to never quite get settled with your stance or aiming etc, but in any case jumping because you knew you missed is generally accompanied by you already having been anticipating a possible miss. There is also some self fulfilling prophecy component to those cases where you were already anticipating a possible miss.
