No. The less skill the players have, the less likely it is that it will matter who goes first. At the grandmaster level, I think the ratio is something like 2 to 1 in white's favor. That's win-loss ratio, not counting draws. That's the accurate portrayal of the strength of white over black, since that removes the variable of downright lousy play. When you're dealing with players rated below 1500 in chess.com rating, I'd guess the ratio is probably around 50-50.

As of today the win rate on chess.com for white is 49.9% and 47.4% for black. Seeing as how so many games are played, isn't this a pretty accurate portrayal of the strength of white over black?
