Low ranks are so pro?

I been playing all day and plus days before this patch I noticed there been a lot of low rank up in alpha and other servers and there all low ranks and there all getting ace and like owning?! I mean there like going 40-13 or 20 -3 and i ask them u all have mains? there like no lol...so Im like wow...but i dont wanna judge on this becz myself came from a game called css and just joined this game like a week ago and i do have a 2.0 kdr or a bit over so idk its just odd and ppl are just finding this game pretty easy i guess. well goodnight all :P
