The water needs time to move out of the way. If you jump from high up, you are too fast, so the water cant get out of the way fast enough for you to noticeably sink into the water on impact. This means you are decelerating from your speed (which is fast, because you’ve been falling from high up) to near-zero in just a few centimetres. This deceleration is what hurts/kills you.
