That's a matter of perspective.
A gold looks godlike compared to a bronze, put me in front of a bronze and I'll crush my lane, farm nearly perfectly, even If i do mistakes you probably wont notice it because I will not get punished for these mistakes.
Put a master to face me and I look trash, he will punish every attempt to farm, i'll miss CS trying to avoid his poke, i'll get rekt, any single mistake I do will backfire instantly.
In the two games I would have been the same player with the same skill, yet in one you would want me in your team and in the other you'd report me for feeding.
When someone feeds in your team : "Omg he's so bad".
When you get fed : "Omg I'm so good".
The brain is really good at finding excuses when we are mediocre, else I think we would all be suicidal, but as a matter of fact, 99% of us just SUXX at this game. The 1% left might have some clue how to play this game, at least the basics.
winners find solutions losers make excuses
Remember this. No matter what your mom did tell you, you are not special.
