What does Lifetime writes mean in HDSentinel?

[Exodias3219]

Hello! I'm going to buy a used Zotac 120gb SSD that has the following data in HDSentinel:

Power on time: 31 days, 7 hours
Lifetime writes: 927GB

I want to confirm if the lower the value of Lifetime writes and Power on time tells you that the SSD is almost new and unused. The seller told me that the 927GB is the writes left on the SSD which is I don't believe in and highly doubt it. Please confirm this thanks.

Yes, that is the total data written. It's near new. It's not a countdown to destruction.
