Where I live "pickles" without any elaboration usually means small picked onions so it must just depend on what the most common type of pickled vegetable is where you are and in the US that's cucumbers.
Btw we call pickled cucumbers gherkins if they're big and cornichons if they're small.
Sliced American style pickled cucumbers are sometimes called pickles but thats the influence of American fast food.
