Legendary vs Pearlescent chances

Is it safe to assume that wherever you can get a legendary item (e.g. a skag pile) you can also get a pearlescent? or is there any exception (i.e. the vases from Tiny Tina’s DLC)

Anybody has any references? …Like a Gearbox statement or something.

No “official” references but I’ve gotten pearls and legendaries in skag piles, Dahl dumpsters and the tiny Tina pots to name a few places off the top of my head. I assume that really any loot source that has the potential to drop a weapon at all could, based on RNG, drop a legendary or a pearlescent.

Most of my pearls have come from the loot train, tubbies or LLMs

What does “RNG” means?
