Not necessarily. A lot of footballers are quite biased, and many of them don't watch football that much (although in Xavi's case, he is an encyclopedia of football).The best way to judge a player is by what his fellow professionals think of him. Awards are all politically driven and also driven by the appetite for that player wanting an award (which Scholes never actively wanted). Scholes was widely regarded as the best midfielder of his time and best at what he did by the vast majority of non English club affiliated legends.
I think that Ballon D'Or award hasn't been politically driven bar on those 4 years or so when it was joined with FIFA award. Incidentally, the value of it got diminished because 1/3 of the votes came from footballers and 1/3 from managers of national teams. I think that journos are better at it than footballers, simply because it is their job to be good at it and to watch as many matches as possible, while players job is to be good at football. A lot of players say that they don't even watch that much football, and you can see from interviews how ignorant most of the players are when it comes to football.
Quotes in isolation don't mean too much IMO, and you can get similar quotes for other players. Fergie for example called Gerrard the most influential player in the league and a better Vieira in 2004, with Zidane calling him the best in the world, etc etc.
I like how Scholes peers' appreciate Scholes, but I think that a large part of it might be because Scholes was arguably the first truly great midfield playmaker, and it is possible that Pirlo and Xavi modeled part of their games to emulate Scholes. However, they surpassed Scholes by the end of their careers.
