If a coin gets devaluation, everything else to the coin becomes more expensive, so yes.

For example: If 100 pesos was worth 1 euro, but through devaluation 200 pesos is now 1 euro, an Argentinian would have to pay up double the amount for the same thing in euro's. So international import is hard because everything from all over the world just got so much more expensive, but export 'should' be easy, because all your domestic products are worth so much less to produce.

I think fossil fuels and diapers just got even more expensive than that, but I don't know why. (I'm bad at economics)

Fossiel fuels are the base for the price of basically everything else. If gas is expensive, transportation costs are goi to be expensive and the products are going to reflect that.
