ELI5: It is said that time gets slower and slower near a blackhole. Does this mean that inside the blackhole there is a point where there time does not exist at all? If something got sucked into that point, would it stop existing completely?

In GR you have to distinguish between the

1. The time a person at point X observes passing at a point Y remote from them and

2. The actual proper time experienced by a person at point Y.

From the perspective an observer outside the event horizon of a black hole time seems to stop at the event horizon. Nothing is ever seen to actually enter the black hole. [This is because the way a person at X observes things changing and happening at point Y is by receiving messages from point Y. The gravitational pull near the event horizon makes it take longer and longer for light to crawl out of the strong gravitational pull. At the event horizon the pull is so strong that light is making no forward progress. From the perspective of someone riding the photon out of the black hole it is like swimming against a strong current, the universe is falling back into the black hole as fast as they can swim out. Hence from X's perspective nothing enters the event horizon... because he can't see it happen.]

In reality, and from the perspective of a person falling into the black hole they do in fact pass through the event horizon and reach the singularity in finite time.
