More specifically, I understand what they are (Voltage is the guide of electricity and Current is the speed of the flow), but I’m having trouble understanding their relation. For example: in a hypothetical scenario where I have a 220v source that outputs 1amp through an uncovered wire, since the voltage is only the guide of electricity, would it be safe to touch?
I also may be wring about the definition of Voltage and Current all together.
All help is appreciated! THX!

A garden hose is moderate pressure (voltage) and moderate flow (current).
A pressure washer is high pressure and low flow.
A storm drain pipe is low pressure and high flow.
120V 20A is the same amount of power (Watts) as 240V 10A. You just doubled the pressure and halved the flow.
And don’t touch a 220V wire. If its max output is 1A, it still won’t be pleasant. But most 220V outlets have the capacity to supply at least 15A, and the flow (amperage) is determined by how much the plugged in device sucks from it. So, how much amperage do you think your body will suck from the wire when you touch it? It’s painful, trust me.
Current quantifies how much charge is moving through the circuit.
Voltage quantifies how much energy that charge carries.
