It's just how random works (https://en.wikipedia.org/wiki/Random_number_generation#Computational_methods). Function takes a lot of different values from current memory (like current online players number, your account id, current server load, etc) and then cache them for faster results. It means you have a very high chance to get the same card from a 10x roll. And it also means that you'll get different results if you wait some time before rolling again. As for getting good card from gacha, it better to rely on server load. During heavy load random function has a great chance to return unexpected result (that 1%).

So yeah, time matters here.
