Just shows how useless that stat is.
Statistics are 100% anything but meaningless. But that is what statistics are, they do not define a moment but rather regress towards a median. Just because we lose a game against x opponent, you can't look at the metric for that game and go "Well well well, stats are meaningless". Even if it tempting to do so, but to go that route is factually incorrect.
Regressing towards a median is in very broad terms where the variables meet after measuring outliers in one and and the other and the set in between. You use the numbers to predict a set of outcomes based on x numbers of stats that all relate to a predefined action such as GA, GF, xG, xP, etc. If the term is long enough, you can very accurately predict anything over a time period, not just accurately predict the outcome of any given action, in this case a premier league match, just a statistical likelihood.
Take the famous coin toss. "if you flip it enough times, it will always land 50/50". This is based on probability. In the real world you can affect the outcome and game the results if you will. This is also true in football, and that comes down to a players personal skill level, which is why, lo and behold, good players perform better than bad ones.
But in short: Stats are important, both averages and performance metrics that influence game stats. Outside of that you have an value close to infinity of actions that can take part on a football pitch (only limited by the plank constant).
So cheere up friend, these numbers count for something! Even if beating Roachdale is a struggle.
