Voltage, electric potential difference, electric pressure or electric tension formally denoted V or U, but more often simply as V or U, for instance in the context of Ohm's or Kirchhoff's circuit laws is the difference in electric potential between two points.

Does current always flow from higher to lower potential?

A source that can supply more than 30V can kill a human.

It is the current that flows in the human body that can kill. That is why high voltage machines or circuits are dangerous. A high amount of voltage that is absorbed in the human body together with it's human body current is fatal.

The current is very small and not sustained. So, it's a little more complex than the old "volts jolt, amps kill" adage. At low enough voltage and with skin dry and intact, no current can even pass into the body, regardless of how high the current is.
