ELI5: Why is it when you touch the metal part of a plugged in phone charger you don’t get shocked?

I’m confused why when I touch the tip of my plugged in my phone charger it doesn’t shock me.

Because it's an absolutely tiny voltage--the charger is probably only providing about 4V, which isn't much more than the batteries in a torch, which similarly wouldn't be able to give you a noticeable shock. (Even the more potent 9V batteries won't shock you if you touch the terminals with your skin--your tongue, on the other hand, is a different matter entirely).
