If i leave my charger plugged in and the switch is on without any device charging, does it ‘waste’ electricity? Why/why not?

Yes. But the amount is usually very small. You can use a device branded a ‘kill a watt’ to measure exactly how much anything that plugs in is drawing at any given time.
It’s also a reason that one of the policies that governments need to pursue to combat climate change is to mandate that any device draws no more than a single watt when idle. When people find out exactly how much power ‘off’ devices actually still draw, it can be shocking.
