There is nothing impossible in this universe.
But every event is associated with a probability factor. And the probability of such an event happening (where Earth falls into a blackhole) is close to zero.
Also its misleading to state that Blackholes eat up everything. Because it gives an impression that Blackholes actively chases down every star and every planet to eat them out like a shark in the ocean, but that’s not correct.
It just has an immensly high gravitational pull, which decreases exponentially with distance.
A blackhole can be compared to a hole in an unimaginably vast golf course, where balls (planets or stars) will only fall into the hole if they approach dangerously close to the hole.
And if they do, there is nothing that can stop them from falling. The only catch is, this hole is not stationary (like in actual Golf course) and moves through space & time.
So, yes its not impossible for Earth to fall into a blackhole, but for that to happen, our solar system has to be in direct line of a moving blackhole and space is just toooo big (even for our Solar System) for that to happen.
Hence, not zero but almost zero probability.
