I mean, you stub your toe, some sort of electric signal goes to spine/brain, right? But if it’s an electric signal, does it carry **specific data** to tell brain which body part got hurt? How does that work?

The data each nerve sends is essentially the same. What matters the most is where it ends in the cortex. So the nerves in the toe that carry pain sensation end up in the cortical area that interprets pain in the toe.
