ERA, thank you for taking care about my reputation
Let make it simplier for you
Suppose you go to Europe, you have to spend some money there. For meals, hotels, rent a car, museums, entertainment and to buy smth nice for your family. Europeans do not accept GBP everywhere, so you have to exchange 700 GBP for 1000 EUR.
Then you just spend this 1000 EUR and never buy back your pounds. (Looks like a small importer to me).
You probably agree that you is part of the forex market while making this exchange. Just explain to silly me have you won or lost, and how much ?
Or you was just break even
