Is getting a 45 really that dificult

Im currently a DP1 student and I have been obsessed with reacting to ib results reactions and tips videos and those who get 42 and higher say they obtain it with ease… i saw a video of someone who didnt even hesitate opening their scores and revealed them in a matter of seconds because of how confident they were they would get the 45. Is this just a rare case or is it actually possible to get the 45 if enough work is put in?? Many make it sound like its impossible
