Maybe for you and for some others users of this forum, 4-star players flying like superman in the middle of the field without any resistance or blockage despite the presence of many 5-6 star players in front of him is 'simulation of real life'.
Maybe for you and for some others users of this forum, players deliberately 'disobeying' the managers orders and 'deliberately' giving the ball away to the opposing team and letting the opponent to run free to the goal and score is 'simulation of life'.
Maybe for you and for some others users of this forum, things that happened in say once or twice in a decade or two in real life are happening 1-4 times every season or two in this game is 'simulation of real life'.
But not for me. This 'simulation of real life' or 'luck' are just excuses. I think it is more due to flaws, poor simulation and/or intentional programming in this game.
Speaking of flaws, so many users have seen how many visible flaws, errors or anomalies are there in this game (especially lately); now, just think about the number of possible flaws that can be in this game that are not visible or that are not easily noticeable, where some of these flaws can affect the outcomes of match results, the performance of players and so on.
