Basic standard of Random Number Generation. A chance of $1/2500$ simply means that there is a reliable chance that you can expect something to drop within 2500 kills. By its nature, this could be exactly right, it could be drastically different (you could get one on your first kill within the criteria, or you could kill 5000 and not get one) or anywhere in between. Very few people have to go the whole 2500 or more though.
