My understanding is that the Indian visa process is considerably more complicated and time consuming if you are of Pakistani descent, but you are unlikely to be denied the visa if everything checks out. I don't believe the government publishes visa rejection rates though, so this is anecdotal.
If you're looking to go in January, I would advise you to apply immediately, since processing can take 2-3 months: http://www.indianembassy.nl/eoi.php?id=Visa-Pakistani
