provably fair audit real?

I keep seeing all this "provably fair" stuff advertised everywhere, especially with crypto slots and table games. Supposedly you can audit the results yourself, but honestly, does anyone here actually know how to verify these outcomes for real? I get the basic idea, seed hashes and whatnot, but it gets so technical.

Feels like it’s mostly for show, unless you’re willing to dig deep into code or trust some third-party checker. For us old-school slot guys, the tech details just kinda fly over my head. Do you folks actually check the fairness, or just trust the casino and hope for the best? Would love to hear if anyone actually caught something fishy this way. How deep do you go into the auditing yourself?
