I need some help with premade animations

Hey guys, new to unreal here. I have been following vitrus hub’s fps tutorial on youtube. During that tutorial, he sets up a skeletal mesh with a custom skeleton. The series comes with about 30 animations that are implemented (running, crouching, dying), and I was wondering if there was a way to hook up my custom skeletal mesh and skeleton to use those animations. I am aware they were animated on that skeleton, so if there is not a way to get my skeleton performing them, is there a way to hook up my mesh to the skeleton with the animations. Sorry if it sounds confusing, I’m not 100% sure how to word it. Thanks in advance for your help!

If there is a better place to ask this question, let me know.
I probably should also note that I have no experience in C++ whatsoever. Thanks!
