Yeah, it can kill you, so can your 12 volt car battery, but neither are considered high voltage.
Now a 12 volt car battery is dc, and even though it has say 90 amps,(cheap batt) it won't kill you. go grab the neg and positive teminals, you won't feel a thing.
Of coarse, it isn't anything like the 660,000 volt dc transmission lines I play with, But if you are stupid enough to think household ac voltage isn't high voltage, even 120, you are just a right circumstance away from dead.
