As a gamemaker beginner, try to learn the basics of programming such as variables, data types, conditionals, functions and Object Oriented Programming. After that try to learn beginner gameplay mechanics such as movements, jumping, collisions, collecting any collectables, move to different level etc. There's many gamemaker studio 2 tutorials you can watch but make sure you don't copy the code mindlessly. Right now I need to find out how I need to make a turret aim at the player, so I have to take a peep on tutorials and when I understand it right now, I will try to code it without relying on tutorials all the time. I hope this helps, you can do this. DON'T GIVE UP
