Question. Does the game favour teams with higher goal difference to win the league

[pcmacdaniel]

I don't think the game engine favors teams with superior goal difference, as much as teams with superior goal difference are just stronger teams. In a small sample size, teams with less quality can and do pull off upsets against better teams and those more talented teams go through slumps, but as the more games are played those statistical outliers tend to regress back towards the mean as everything averages out.
