Understanding the rules

Do the devs of EA FC understand the rules of football or do they just make them up in their head? I'm so tired of being given a hand ball from a defender who has their arms at their body and is clearly an accidental touching. This happens at least every other game and results in a pk for the other team every single time. It's also beyond obvious that they have things programmed into their game for squad battles that does these things in order to make you lose points by allowing the other team to score. You can do everything right and their AI system will still find a way to make you give up a goal.
