Google and you shall find.
No really… Google. However i would try out the beginners tutorials Epic games has available. Get aquianted with the editor and take it slow and try small things.
Ignore most of all those words you mentioned. Unless ofcourse you want to be a 3dmodeller. Then i would head over to www.polycount.com where a lot of talented people hang out + they have some very good wiki’s on those definitions.
And finally there are youtube. There are so many good beginner videos to look through.
Eventually you’ll get the hang of it and figure out an area you want to dive deeper into. Just take your time and learn things bit by bit, don’t rush through it… it’s eventually gonna burn you out. I’ve personally worked with UE4, ipisoft, motionbuilder, 3dsmax, maya, mudbox, quixel suite, megascans, zbrush, xnormal but all in just for isolated things. I started with this 1 year ago, and i still only do prototypes of stuff i want to try in order to self-educate. I don’t say it’s gonna take that long, but personally im a generalist and like to get my hands in a bit of everything so i know what it’s about. At some point i will have to settle within an area which i think most people do.
Good luck with your journey. Its a great one if you remember to enjoy it
