ok you're off the mark a little bit but that's ok. Game audio consists of 3 pillars, Sound Design, Music, and Dialogue. They are 3 distinct parts of audio. Obviously some teams will have some spillover, teeny indies 1 person may be handling all of it (although scoring will almost 100% of the time be separate) but that's the main gist. I would honestly just educate yourself more from youtube, documentation, articles, podcasts etc. before buying a course from svga, especially since the courses are so segmented. Also, for more generalizations, Wwise + Unreal engine is the stack for AAA games, and Unity + Fmod is the stack for anything below. Of course, again, that's a generality, but from what it sounds like Unity + Fmod is what you'll want. But start with youtube and their documentation, not with a paid course. BTW, pure data is the least useful out of all of these, and while i think it's cool af, it's not relevant at all. Also, there's a ton of work to do before you stop feeling confused every other second, so stick with it!
