Yes, there’s a difference between liquid and dry measuring cups. While the cups may hold the same amount in volume, they have been engineered to precisely measure their respective constituents. While you may get away with interchanging these cups when cooking, do not switch the cups if you are baking. The tiniest differences in baking ingredient measurements will affect your final product. Dry measuring cups are usually filled to the brim and the excess is swiped off. Liquid measuring cups have calibration lines below the rim to measure the meniscus of the liquid.  If you use a dry ingredient measuring cup for liquids, you’ll have to fill the liquid to the brim. And you’ll most likely spill the liquid as you add it to your recipe. Furthermore, you’ll scarcely find a dry food measuring cup that is larger than 1 cup. Liquid measuring containers can measure up to 8 cups. A digital scale will accurately measure both dry and wet ingredients.
