Avoid trying to guess/predict how someone who's not you deals w/ a lifelong chronic illness. In a perfect world every person with diabetes would be rigorously testing and in total control of their blood sugars. This isn't always possible and isn't always what the person wants.
Personally, as a person with Type 1 Diabetes who has relatively good control, I am much more worried about DKA than an unexpected low. Modern insulin analogs are very predictable and I eat a very structured diet. I wear a CGM and am very aware of my #s. It's much more likely that illness or some other factor will send me into DKA than an unexpected low will kill me.
This isn't true for all people with diabetes though.
