Question about Microsoft 365 Single

Good morning, can someone kindly help me clarify a doubt? Are "Single" (like the one sold here) and Personal the same thing? Because I see offers online for 365 Single and 365 Personal and I don't understand if I am buying the same thing...? I have Personal subscription expiring in 7 days and I don't understand if I can also renew it with a "single" thanks a lot in advance
