Yes, but that’s very localized and it’s not the same as the image some people have of black holes characterizing themselves for instantly sucking it all in its vecinity.

If the teachings don’t reach outside the classroom, you wouldn’t say that people outside can learn more standing there than they would from any other similarly looking room. For a black hole, the gravitational pull over everything that you can see around it is the exact same as it would for a lower density equivalent mass you might be orbiting.

And we know there are stars heavier than some black holes, which actually would have a stronger pull to things in their proximity than if they were a black hole with smaller mass. Also Stephen Hawkins introduced the concept of micro/mini black holes. He theorized that the minimum mass for a black hole is in the order of 0.00000001 Kg. What makes a black hole have a singularity has more to do with its density than its mass, so if you could smash together a mass with enough strength you could cause it to collapse.
