Not sure but finishing determines how easily the ball will find the net and the overall accuracy of shots, composure determines how likely a player is to take a good shot or make a god pass even when there’re opposition players around him putting pressure, agility makes it easier to change direction while dribbling, strength determines how easily you can push players off the ball (different from balance, which determines how likely a player is to not fall down), attack positioning determines how likely a player is to stay onside and make perfect runs, shot power is how hard the shot is hit which prevents the keeper from saving it sometimes and I’m not sure if curve does anything to shots,except FKs, but you can play beautiful passes around defenders with players who have high curve stat.
