Math + Reading = Poker
The two largest broadest headings of types of poker skill are knowing the math and odds in a situation, and being able to read the situation. Most poker books
focusing on math, or reading situations make it a point in their introduction that both abilities are needed to play at the top levels.
The short answer is that none of the big time professional no limit players are not good at both aspects of the game.
The long answer is that no one who doesn't bleed like a stuck pig doesn't use both. The two facets are symbiotic. If you didn't have the ability to read an opponents actions, at least a little, then you wouldn't know how to apply your math. Inversely if you didn't know any of the math, at least the bit that is intuitive, then you could never use your knowledge about what your opponent was holding to make them make mistakes.
It is possible to be a slight winner/loser with a very good understanding of one of these concepts, and only a ruidmentary understanding of the other at lower levels, cutoff for what is a "lower level" to be left open to argument. However you'll die in a big games, and you'll never really do well long term in even the smallest games without a solid understanding of both aspects of poker.
That being said individuals may well lean more heavily on one skill than the other, but it's hard to say sometimes if someone is doing this, because really every decision, except for some pure math ones, rely on information from both disciplines.
I specified no limit, because I think that you can rock math pretty hard in limit, but even there you need to figure out when you're drawing dead, or how many of your outs you ought to be discounting, which takes some situational knowledge.
