It’s more accurate to say that gravity bends spacetime. The light we see being bent around a black hole is a consequence of that, and is evidence for time dilation as it is also evidence of space dilation. And (being extremely pedantic here, I know,) gravity bends spacetime and light travels through that spacetime in a straight line.
Being in any gravity well will slow your time ever so slightly, by the time you die your feet will be about 100-500 nanoseconds younger than the top of your head due to being closer to the earth!
