No, that is not the reason that they cannot escape. Take a look at some of the similar discussions below or ZapperZ's statement in this thread.ganguly pranav said:If black holes were able to stop light from escaping , then would it mean that photons do have a certain mass (no matter how much negligible it is )
This issue has been discussed to death in several threads in both the Quantum physics forum, and the SR/GR forum. Please do your search there and figure out how gravity is a spacetime curvature, and why light follows the "geodesic" of that spacetime curvature. It has NOTHING to do with light having a mass.

A black hole is a region of space where the gravitational pull is so strong that nothing, including light, can escape from it. It is created when a massive star dies and its core collapses in on itself.
In a black hole, the more mass there is, the stronger the gravitational pull becomes. This is because mass is what creates gravity, and in a black hole, the mass is condensed into an incredibly small area, making the gravitational pull extremely strong.
Black holes have an immense gravitational pull, which can bend and distort the path of light and photons. This phenomenon is known as gravitational lensing and can be observed when light from distant objects is bent around a black hole, making it appear distorted or magnified.
Photons are particles of light and are considered to be massless. However, they do have momentum and can be affected by gravity, as seen in the bending of light around a black hole.
The speed of light is constant in a vacuum, including in a black hole. However, the intense gravitational pull of a black hole can slow down the passage of time, making it seem as though light is moving slower. This effect is known as time dilation.
