Example -
Riolu only needs 1 exp for level up and evolve, he gets poisoned in battle and he faints the opponent making Riolu leveling up and evolving into Lucario.Lucario is a Steel-type making it cannot be under poison..
Would Lucario get poison or get rid of poison?

Even though it cannot get poisoned any other way, it wouldn’t just go away.
Non-volatile status conditions, officially called status problems, are status conditions that will remain until a Pokémon is healed at a Pokémon Center, a specific curative item is used, or, in case of freeze and sleep, after a certain number of turns during the battle.

Lucario would still be poisoned after evolving from Riolu, and will still take damage from the poison
