AI Auditing am I just running into another buzzword?

So recently I was complimented quite extensively on how well/fast I put together some niche training data sets. Which I thought was weird because most of it was just applying the same OSINT principles I use when it comes to verifying data. However he was insistent that it was top tier work especially for how much I had to go through and that places pay good money for datasets etc. Of course when I asked ChatGPT it gave a glazing answer but did put up some of the expected growth numbers. It also introduced me to the position and field of AI Auditing and dataset auditing. I looked into it and found a bunch of certs(AI RMF, CEET, AIEd) and it look interesting but like.....

.......is it just another buzz word kind of deal? Was that dude blowing smoke? It was about 1.2 million words worth of technical data I stripped away the copyrighted material and anything non-use. They didn't give me a template so I looked up a few different ones and curated my own. Then I just ran it through a few tools to double verify before packaging up and sending out. So like......it really didn't feel like a big deal. Are good datasets that big of a deal?
