Oh, I get it now. Basically you are just stating the obvious that statistically you are more likely to pick up points in some games rather than others. E.g. Man City will more likely beat Palace at home than United away.
We'll beat teams above us and lose to teams below us. As do all teams, or else we'd all be millionaires.
There are distinct exceptions and teams clearly change places throughout the season, so restrospective 'facts' on the whole.

Finally, someone isn't over complicating things.
