Is the motor destroyed ?

I consider this to be wrong . That's what the multimeter says :
when I hold the pins on the air , it's 0 . When it's on wood , it's 0 . On paper ? 0 . On a closed circuit ? 0 . Maximum resistance .
Not even the most expensive of all can measure some stuff and no multimeter does know the fact that
NOTHING HAS ULTIMATE RESISTANCE AND NOTHING HAS 0 RESISTANCE , EVEN A PIECE OF GOLDEN WIRE HAS SOME RESISTANCE , AND A PIECE O' WOOD IS CONDUCTIVE WITHIN 99999999999999999999999 VOLTS .
But max resistance is in the sense of little-dc-power-not passing . Like oxygen . Wood . Glass .

You're wrong.
You obviously have no electronics experience.
Post a photo of your meter in resistance mode measuring the motor winding. close up enough to see the meter display.

Prove to us that you know how to measure resistance. Post a photo of the resistance of a 220 ohm (or any other value ) resistor.
THEN, post a photo of the resistance measurement of the motor leads.

On a closed circuit ? 0 . Maximum resistance .

I'm sorry to say, this statement seals your doom. The problem is you do not know what resistance is.

Think about it.
This statement:

On a closed circuit ? 0 . Maximum resistance .

Should read:
On a closed circuit ? 0 . Maximum CONDUCTANCE. (MINIMUM RESISTANCE) (NOT MAXIMUM)

And this statement:

when I hold the pins on the air , it's 0

Should read:

when I hold the pins on the air , it's OPEN

Either way, until you post a photo of the meter reading a resistor, the only conclusion we can draw is that you have no understanding of the theory of resistance. (or conductance) (or you have confused the two)
