Play stupid games, gain stupid prizes.
People, even these days will never truly heed that ELECTRICITY uses WATER as a CONDUCTOR.

Emanel is an insulator, the conductive variant is usually laced with metals and more an industrial thing. The only time your run of the mill bath tub is conductive is if it is either a rustic one, the coating is broken or the at least the drain is metallic and grounded. That was alot easier back in the day when everyone was using metallic piping. Today though with PVC or PE piping being more common it is far from guaranteed that a system like that would actually work. Especially in renovated places I wouldn't bet on someone having bothered to somehow ground the drain by drilling a couple of holes into your wall to get a decent PE connection there, if that is even possible (they aren't all metal either these days).
The point I was trying to make is that people should not trust blindly in RCDs (because some here sound like that it alone would have saved his sorry ass), there are a lot of factors to consider and while RCDs have helped to reduce death by electrecution by 50% and then some, it requires certain conditions to actually protect you. Even with protective devices, electronic appliances connected to mains have no place anywhere near your bath tub. Especially something as dumb and useless as charging your phone inside the filled bathtub.
You are missing the fact they work and in some cases, a GFI is mandatory by code in bathrooms with a bathtub or shower. And water will conduct electricity and act as a ground. You can not have a good ground connection outside a house if the grounding rod is in sand with no water present. Which is why the rods are driven fairly deep to make sure there is contact with the moist soil.
