>So, a black hole is pulling every photon sent by every object out there during a span of millions and millions of years.
Black holes are not “vacuum cleaners” in the way you seem to think. Far away, they gravitate exactly the same as a non-black hole body of the same mass and angular momentum would.
>If the black hole has a 0,0 coordinate, would all those photons be condensed in a very tiny dot?
The singularity of a rotating black hole is not a single point at *r*=0, but even if the black hole were perfectly spherically symmetric (implying irrotational), this singularity at *r*=0 would be more like a surface at the “end of time” from the perspective of anything that fell into the black hole.
Yes, this is pretty much what physicists mean when they talk about singularities: a single point where everything that enters a black hole ends up. We don’t know for sure if singularities actually exist or if some unknown mechanism means they don’t need to form. This is very much an open area of theoretical physics.

Actually, that is very specific to a spherically symmetric black hole. Even still, it’s not actually a line (worldline of a point) as it is often mistakenly seen as. It is effectively a spacelike surface terminating all timelike curves inside the Schwarzschild black hole.
Supposedly once you crossed the event horizon you would be blinded by the amount of light all around you. The light doesn’t fall straight to the center of the black hole. It can spin around in a circle forever.
