Not necessarily, it depends how it was wired, and IT IS VERY DANGEROUS to assume that any particular wall switch was wired to kill the power to whatever it controls. (Such as a light fixture or a socket outlet.)
The only safe way to kill the power supply in your home before you do any work on anything like a light fixture, a socket outlet, a kitchen range - or anything else! - is to switch off the big "main switch" on your home's breaker panel.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

A loose kill switch wire on your out board motor will cause the engine to lose power. As the kill switch loses contact the motor will begin to bog down or completely quit.
Open up the ceiling box and disconnect the blue wire coming from the light and connect it to the black wire coming from the fan. Be sure and put a wire nut on the wire where the light was connected before you removed it. The wall switch is controlling power to the wire where the fan is connected so when you connect the blue fan wire to that connection you will be sending power to both the fan and light from the wall switch.
When you switch off a 3-pin power socket, the socket and connected devices are no longer powered, but the socket still remains earthed. The grounding connection provided by the earth pin is separate from the power supply and remains connected even when the socket is switched off.
If you are referring to a switched UK-style socket outlet fitted with a led, or a wall switch fitted with a led, then the led merely indicates that the socket outlet switch or wall switch is in the 'on' position.
