SharePoint Online Multiple Sites?

Question

I've just published a SharePoint Site and it seems there's not just one, but many:

URL                                                STORAGE USED (GB)    SERVER RESOURCE QUOTA

https://example.sharepoint.com                            0.00              300
https://example.sharepoint.com/portals/hub                0.00              0
https://example.sharepoint.com/search                     0.03              0
https://example-my.sharepoint.com                         0.00              0

The question is why are there so many instead of one? If I need to delete it, will I have to delete all? Also, the last one seems strange.
