Should I move along and hope that things get clearer for me in the future

The tutorial you watching and documentation wasn't done in a day, it took the author months or even years to archieve that far, at least give yourself a kudos, there are many out there who have spent several hours looking at a tutorial file and still unable to understand what to do but between such a short period of time you have been able to pick up some steps and the intro not so new to you anymore.

The best advise would be to keep practicing till you master it, cause then others will just flow in smoothly skipping any now would lead to more confusion later on
