They probably are doing many of these things (Karting excluded) but the lines between speed and failure are much tighter and harder to traverse in the wet.
Verstappen and Riccardio are very late on the brakes and make (some!) great deep overtakes, but not everyone can do it well.
The risk level is high and if a driver cannot do it intrinsically they won't even be thinking about the opportunity.
It's proven that elite athletes use less of their brain for things they have practised more than others. This leaves more of the brain capability for thinking outside the box and allowing conscious use of alternative techniques to gain an advantage.
I took part in a study to compare top level sports people to novices using an FMRI to compare reaction to external stimuli and having to calculate a response to that stimuli.
They blood flow and "work" of the brain of the top level athletes was significantly lower than novices.
We were even asked to react to an unfamiliar stimuli from another sport, and STILL the top level athletes out performed novices, but the gap was narrower across the range.
The point is, these phenoms of speed are capable of doing incredible calculations and reasoning that allows excess brain power to be utilised to do special things that others can't.
You should watch "Tested to the limit" where they tested Ronaldo's ability to score in some unusual circumstances. It gives some insight to the levels of ability on tap to the best sports people.
Watch it here.

Zoe (the lady doing some of the testing) is a friend of mine and her study was the one I referenced above.
