You still have chance, but it has been said that the probability of rare drop is lower with A rank compared to S rank.

Bear in mind that map difficulty can also play a part. There have been cases where rarer shipgirls may drop only in a specific node with specific enemy formation, and specific battle rank (looks back at Prinz hunting in Summer 2016, and shudders).
