Football is more of an entertainment, only for those that have seen it in such manner, because from last season and as you have said, it was never believed that they would have gone that far from the way everything started, which is football for you, i also observe that the same PSG have been panting over the UCL title for long and never got it until their time reached last season that they surprised everyone and made it at last.
I think there are teams that are a bit of a favorite and others that are very lucky, PSG have had a lot of luck this year, thanks and thanks to Donnarumma they have come very far and then managed to win the cup, without him I don't know if they would have succeeded
