ELI5 How do people die when they jump from bridges into water yet there are plenty of people who do this for fun?

I assume you are referring to people jumping from the same height so basucally what it comes down to is experience/training. Hitting the water from significant height means a person is traveling quite fast. Faster than it takes for the water to move out of the way. There are positions and techniques to mitigate potential damage. Also there is a mental aspect. If a person hits the water and isn't prepared for it they may over react or panic, they may get disoriented and swim down instead of up, or they may inhale involuntarily, etc.
