I kind of agree but 1,000 games is still a lot (whether they are only wins or just games in general). I think people do need a better understanding of how the game works before playing Ranked. When I first got to level 30, I jumped into ranked and played 8 matches and only won 1. I did not have map awareness, skill, knowledge (about items, champions, masteries), I didn't think runes mattered, could not CS, barely warded and could only play around 5 champions decently at the time. I definitely did not have a good experience with ranked because people obviously didn't want to play with someone with me (which is understandable). I didn't play ranked anymore (this was during season 3). I spend the rest of the year, plus the first half of season 4, learning League more. I went back into ranked towards the end of Season 4 and was placed in Bronze. I played a lot of matches and learned a lot during that time and did eventually make is to silver (I know it's still not that good).
I think players do need more knowledge about useful things like map awareness, knowledge about items and champions and can play a decent amount of champions. Fortunately, they can learn from playing ranked matches, which is unfortunate for people that do know how to play, even if they are at bronze level.
