If chests showed up as "Chest (Empty)" instead of "Chest", then it was your friend. If there were no chests and all of the corridors were dead ends, that's RNG. You can get 20 cores and a TON of skellies in a burial chamber or you can get nothing at all. RNG has nothing to do with what you're used to or what you've experienced.
