As a average-good CS:GO player i find GeT_RiGhT so strange, but he is lan-proven and i know it's possible to be a god in something.
I saw fastpaul, supergaymes, alex, wangster, zuq, egggrunge, mcdonald, gorny, and some others become a beast, i remember when fastpaul was just an average player, when supergaymes was finishing in 10# in almost all tracks, when zuq was asking me on /pm how to play good (i know i never played good but whatever), when mcdonald was playing so bad...
I don't have a high skill cap to play CS and GTA at the highest level, but i have beat some top1s (one of them was in a really old race, but with a fake account
http://highscores.adrenalinex.co.uk/full/NeedleinMyVains ), so i know it's possible to play at this level, but you need to practice much more to be that consistent.
