as someone whose played at an elite level in rugby, I can firmly say that in any sport/eSport you need to be gifted and work hard to get better.
Never played with another fellow international teammate who was simply gifted, or simply talented, both are required to compete at the highest level of play and that's why the skill ceiling for high level play in anything is a low % of the total pool of players. Not everyone can achieve both of these things, I've played with some really really hard working rugby players in my life but they will never be remotely as good as some people if they don't have the natural skills to go along with it, and this most DEFINITELY applies to video games as well.
As clockwork stated before, some people are gifted in certain ways that aren't necessarily as valuable overall, but they can fill specific roles or niches that a team needs in very specific situations, but true star players in spots and in games are 100% naturally gifted and hard working.
That being said, natural talent can only take you so far, something I learned through my time playing international level rugby too, there comes a time where there will ALWAYS be someone that wants it more than you do, and they are the superior talent.
