Photons don't gather energy and they definitely don't move slowly through the sun.
It can definitely take millions of years for photons to leave a star due to dense protons causing collisions.

I get what you're saying but taking a long time is not the same as moving slowly
v = d / t, so technically it is.
but the distance the photon travels is very large, just in random directions
I know I was being pedantic about your comment because I thought it was kinda funny interpreting it out of context.
Slowly making their way does not equal moving slowly. It describes the time it takes to exit the sun, not the speed of the particle.
They’re also rapidly making their way and taking a long time.
And cold wind is when slow-moving air hits you at a fast speed.
fair enough
You are right that they don't gather energy, but they do multiply. What would be a single high energy x ray in the core will eventually downscatter into an army of optical photons.
For photons, their moving relatively slow from the inside to the outside of the sun. Although, I think, it's technically a bunch of photons bumping each other into existence.
They kind of do. While the photons inside the Sun move at a very high speed, they can take up to about 170,000 years to get from the middle of the Sun to the outside, because they change directions a lot on the way.
also temperature doesn't really exist at that scale.
