You're still on Sales Hub Professional or Enterprise.
You have an assigned paid seat.
You have sales permissions.
There is also a new beta which essentially turns the prospecting workspace into the sales workspace. If you're seeing sales as a workspace where prospecting used to be, you're in the right place.
