No, in most cases you cannot know if someone is wearing a thing under sweatpants.
It depends upon the color of the jeans and sweatpants someone is wearing as to whether or not you can see if they are wearing a thong through those pants. If they are wearing white jeans or sweatpants, you may be able to see the thong through the clothing. If the clothing is dark colored, generally speaking you wouldn't see the thong through them.
