Are Neutrinos not faster than light?

Scientists keep proving that neutrinos do not travel faster than the speed of light.
Well if that is the case, in case of a cosmic event like a supernova, why do neutrinos reach us before light does?
What is obstructing light from getting to us the same time?

The supernova really starts around the core, releasing a burst of energy in light and neutrinos. The light gets scattered inside the star, continually being absorbed and emitted taking a random walk to get out. Neutrinos don’t interact with matter much so basically pass right through. In a vacuum light is always faster, but it needs to escape the star first so the neutrinos get enough of a head start to reach us first.
