...it got better?

(This is a famous quote from Monty Python:

)

Whoever made this needs to learn how to form coherent statements.

Indeed. I'm pretty sure whatever is being communicated is probably interesting, but I can barely grasp it.

I think (and IANA astrophysicist) that they are saying because of the density of the sun, the forces of gravity are so strong at the core, that time dilation occurs, making time at the core pass more slowly than time at the surface. Over billions of years of existence, that adds up.

Yeah I was trying to figure out this as well. It's about gravitational time dilation. The increased gravity at the center of the sun means that about 25,000 fewer years have passed there than at the surface, since the birth of the sun.

older. The core is older. It was there first.

This is the correct answer. It's just frustratingly difficult read.

They both formed at the same time, none came first.

Due to general relativity and the immense gravity inside the core of the sun it is in fact 39,000 years younger compared to the outside where time flows faster.

What about convection? There's been at least some mixing, right? So I'd guess the average age of a nucleus from the core (ignoring fusion) would indeed be less than from the surface, but I would think it's less difference (on average) than the raw math. If there's enough mixing it could be very little difference at all.

Oh. You're one of the "time speeding up and slowing down" guys. Oh my. Yeah, that's a real problem. What's your take on wormholes?
