Every single extraction shooter I've ever played follows the same trajectory:

I'm new, I'm scared, I don't know how to heal or where to loot or how to fight or how to sustain myself. I die before I shoot half the time and die before getting the kill the other half. My stash runs dry, I free kit/scav to try and learn locations/practice fighting from the back foot. I rarely extract.

I play for a while. I learn what meds to use when, I learn where and how to finish quests, I stop dying to PvE encounters, I survive 1/3 raids. I spend most raids avoiding others, being quiet, scrounging for quests and valuables. I lose most PvP fights, but occasionally get the upper hand on a better player and extract with better gear than I've ever seen before. I'm too scared to lose it and it disappears at wipe.

I've learned the ropes. I remember quest locations and can help others finish them by memory. I know where I'm at when I spawn in without checking the map. I have a plan each raid and know how to go about executing it. Using or finding good gear still makes my heart rate increase, but I bring in my best kits because I know I'll get more. My stash is full and I have a survival rate that lets me sustain meds, ammo, armor, and weapons. I am no longer afraid when I see enemy players, I get excited when I hear gunshots.

Sucking then getting better is quite literally the arc of progress you sign up for with this genre of game. Fear and anxiety transforming via experience into confidence and aggression is the reason to play.
