How does it draw the exact current it needs? Is it as simple as that because my headphones just have resistance of 5 ohm?
And also, my 5V2A charger can charge any 5V devices that draw current equal to or below 2A right?

Ok I will try to ELY5:
Imagine the charging circuit als a water pipe. The Volt give you the pressure your pipe can withstand without bursting and the amperage give you a rating of how tick (inner diameter) the pipe is. If you have a tap the has a pressure of 5V and a tap size of 2 Amps there is enough water to fill your 1 Amp pipe. And since the pressure from the tap matches your pipes rating, it won’t blow up.
If you now have a device that needs 5V 3Amps you can still try to charge it with your charger since the pressure (volt) rating is the same but depending on the device it will charge slower or not at all.
