You have a 10% chance on every income collection of getting a rope. The drop rate is a long-term average, which will approximate the expectated value of 1 rope per 10 collections. But you can have strings of 'bad luck' where it might take 20 or even more collections before you get another rope, and you can even get two ropes after another with 'good luck'.
