Roguelike is almost never really used properly, as it should be a turn based, procedurally generated dungeon crawler with permadeath and no permanent upgrade system that makes the game slowly easier.
There's maybe like three games from the last decade that actually fit the definition.

Which is why it mostly changed to be Roguelite which pretty much just means "there's 'permadeath' but you gain exp/money to unlock buffs and you repeat until you manage to finish a run". It's used to very quickly explain the main gameplay/progression loop of any genre of game it's attached to.
Kinda like how we use FPS because calling them all doomclones makes no sense - we just didn't pick a better name this time.
