Not really to no.
The problem is that a lot of League is highly contextual. For an extreme example, let's say there's a champion with a 100% win rate in Pro Play. Broken right? What if I told you that champion was picked once against another champion that he hard counters? A lot of sites do well to explain as much context as they can and others, well, don't, but that's really it. You'll never get enough context to apply to what you want in the way you're asking for.
With that in mind, as a new player, I BEG you to consider improving yourself as a player before hardcore focusing on any given champion. Learn to get high amounts of CS on virtually any champion, learn how to A Click and Orbwalk properly, learn the basics about animation canceling, learn the mechanical differences between fighting a duel and fighting a team fight, and most importantly of all you need to work on your macro gameplay.
It doesn't matter who you main if you yourself suck at the game. That is a fact, context and all.
