For OG xbox, I was a definition script kiddie but I learned how to use FTP, how to connect via crossover cable, how to solder, the basics of what exploits are and how they work, and a ton of other skills that I use daily.
X360 required me to take the damn thing apart (which was terrifying as a 14 year old who wouldn't get a replacement if I broke things). I learned about firmware, SATA connections, the bits (I forget the name) that specify whether something was retail or not, why the exploit wouldn't let you run unsigned code, etc.
I was just a broke kid who wanted to watch movies and play games I couldn't afford, but it literally got me into tinkering and hacking, even though what I was doing wasn't much more than "follow a guide, script kiddy"
