Resumephobia

I am in 1st year and When i look at resume of my some senior , there are projects which looks so weird , i mean when will i even learn all this , all i did was cpp , python , started dsa till now like wth is SciPy,OpenCV,Flutterflow,flask,media pipe ,etc ....i mean there are literally uncountable number of things , so do ppl really learn them or they learn them while making the project ?
