Yes, you have one lot registered. So you should now receive one lot.
It doesn't always have to be from a different person. Rarely, it may happen the same person will send you their lot (it's more common at the 50/25stamps versions of the site where there is much fewer members).
Your name will not appear on the main page yet. The main page shows lots that arrived, not lots which should be expected / are in progress. Only when you get someone's lot and register it, will your name appear on the main page.
