Receiving stolen phone scam texts, but my phone wasn’t stolen

I know that this exact scam has been posted about before. I blocked the number before screenshotting what they said, but it was identical to this screenshot I got from another user. I’m confused because this known scam targets people whose iPhones have been stolen, but I’ve never had a device stolen. I’ve gotten multiple of these texts from different numbers with the same image. Why am I being targeted and what are they hoping to gain here? The device they reference in the text is a phone I sold to T-Mobile that was unlinked in front of me by an employee in the store.
