Is my entire game condensed into the .apk file for Android?

I don’t really understand how the .apk and .aab files work. My game is 1.4gb as an .obb, but my .apk is 47mb and is the only file I can upload to Google Play Console.

Is that 47mb my entire game? That level of compression is…unfathomable if so. If not, how do I upload my .obb or .aab (which, still, is only 100mb)?

I don’t understand this pipeline despite reading the documentation and if anyone can shed some light it would be much appreciated.
Thank you!

Google Play console requires aab files. I’m struggling to get my aab file size down.

Aren’t there two ways to do it? You either get your AAB <100mb or you upload your AAB and then OBB files later, as an expansion?
I can’t really figure out how to do either.

I don’t know how to split it either
