What does One Need to Become the Best in the World at Poker?

what do ppl like phil laak or ivey...or brunson etc. have which makes them unbeatable...the best. i started new, I feel like i might have quite a lot of room to improve. Phil laak said he was at this poker club and he started playing and once he got it he broker the record for winning the most in a day or something. So what do they have?
