What do you know about statistics? That sample size is way too small. Look in any database with thousands of master games and you will see that white always does slightly better.
By your logic if I were to take a coin and flip 5 heads in a row (not that hard to do), then I should assume that the coin is more likely to come up heads than tails.
Yea, thats like saying if you flip a coin 5 times and get heads 4 times and tails once then somehow we should challenge the idea that coins are 50-50.
Tal-Memorial 2013:
White wins: 6
Black wins: 11
If it's possible to have results like that at top-level, it doesn't really look like the first-move-advantage of white can be that big and could actually be more of a psychological one.
