So basically it's "lucks".
I think artificial lucks happened more than natural lucks which is very rare in comparison.
Artificial lucks, engineered i.e. determined by players, managers, rules, refs, officials, etc that favored one team or certain players. We can make our own lucks eg. continue attacking would meant maintaining the chances of scoring and possibly winning (matters of mentalities eg. 99 final), attacks more and closer in and around the box with paces and trickery would meant higher chances of getting chances to score and penalties (United this season), exploit the weaknesses of rules and refs/linesman (diminish a bit by VAR and goal line technology except for the 50/50 and human errors), seeing problems repeating and doing nothing about it, incidence like the balloon goal is when no one interfere to swap away the problem or potential problem before it happened, shoot many and eventually one will go in, etc etc. Can also include corruptions and match/fixture scandals that remained hidden for now.
^ None of those are 'real lucks'.
Natural lucks are the things that happened bizarrely often by chance. Usually injuries to naturally fit players, freak injuries or sudden diseases/illnesses, or something bizarre like karma happened to certain teams, managers or players for the bad things they did before. This is where the "football gods" have influences. Thing is, this rarely happened and not exclusive to just football.
