Very new to the UGC world

And by very new, I mean I haven’t started but would like to. Perhaps my interest is piquing with the infiltration of all the UGC courses for sale on my algorithm. Do I really need to buy a course? I’m a stay at home mom, don’t really feel too comfortable on camera but not against it, just want to try it out and see how it goes. How do I get started? Are there tutorials on YouTube?
