if can drive off with parking brake engaged, does that mean that it doesn't work? (Would a working parking brake prevent you from driving?)?
or why this isnt true? if i can drive off without even knowing it is extended or engaged,,,,does that mean it most likely is useless to hold a vehicle on a hill?

A working parking brake "might" prevent you from driving. Although, I have never had a car or light truck, with a working parking brake, that could not be overcome with a bit more pedal to the metal.
That said, find a safe place, with an incline, stop your car/truck, apply the parking brake, put it in neutral, and see what happens.
If it moves, the P.B. is ineffective and should be repaired.
Also, find a flat road or parking lot, then safely go 2-3 MPH, put the car/truck in neutral, then apply the P.B. to see if it works even a little bit. If yes, then if it's applied when your driving, premature wear and failure will happen. If no, the P.B. will not affect the brakes at all.

Maybe. Maybe it's not being applied properly.
Would a working parking brake prevent you from driving?
Generally yes. It would be very obvious that something is abnormal.

The parking brake may need adjustment or repair.
You may need to be shown how to properly apply the parking brake.

Not really. The parking break wasn't intended to keep the vehicle from driving off. Just to maintain it's position when parked. The horsepower of the vehicle can very well overcome the efficiency of parking brakes ability to hold the vehicle in place.

The lever was set but not set hard. If it was set hard you would not move. If it is more than 3 clicks then the rear brakes need adjusting. You have to do a complete test.

Yes, that means it's not working. Chances are you need new brake pads or the park brake cable needs adjusting. As I told you before, these things are not irreparable. If you can't do it yourself a mechanic will fix it without difficulty.
