Black holes are just regions of space where the gravity is so high that it causes space and time to curve back on itself taking any and all exits with it. In other words no escape.
Another way to look at it is all objects have escape speeds. For example let's say Earth's escape speed is 100 mph, then to escape Earth's gravity an object would have to travel faster than 100 mph to leave the planet entirely. The difference between a black hole and Earth is, a black hole doesn't have any escape speeds. Not even the speed of light can escape.
