None of the first three bits are absolute proof that the drive is going,
but they're certainly cause for suspicion.
Why do you think these values are suspicious? My impression is that some
huge values are usual for these attributes. Drive firmware reports that
VALUE is well above THRESH, so it should be normal for a HDD that is in
use for some time.

I have been watching my HDD's and SSD's with smartctl(8) intermittently

still work, while failed drives can produce statistics above the "bad"

Not all failures are predictable. Consider SMART just as a hint, a
technology that may warn you is some cases. E.g. growing
197 Current_Pending_Sector
198 Offline_Uncorrectable
are really alarming even with low absolute values.
