youre in a friends pick up truck when it stalls on a hill. you jump out, get nehind the truck and push with all your might 300 newtons. still the truck slowly rolls back down the hill. whats the pressure the truck exerts on you.
The "force" the truck exerts on you is 300 N. That is Newton's third law.
The pressure depends on how squishy your hand is.
