I looked it up and calculated the exact chances:

White Warg: 0.2% (1/500)

Black Warg: ~4.990%

Gray Warg: ~31,746%

Brown Warg: ~63,064%

So spawning two hundred wargs will not be enough. If you want to get a white warg and are willing to use commands, you can /summon it:

On the same way you could also summon a warg with the fire/ice/obsidian warg skin.
