"Marbles" here refers to the small, glass balls that are played with as toys, used in games, and sometimes collected by people. The word "marble" as a noun is usually used in reference to the "marble" toy. In this case, people usually say "marbles" plural. However, "marble" can also refer to the crystallized rock which is often used for countertops or furnishings in houses.
