Oh man, I am not the guy to ask that haha, just using some preliminary knowledge. According to the Fossil wikipedia though, a fossil is considered such if it is older than 10,000 years. What we’re looking at is apparently called an external mold, where something embeds a mold of itself into a rock. I haven’t been able to find any info regarding how long these things take to form, but most examples I see are tens of thousands of years old.
So I would guess that rock/mold is thousands of years old then. But you’re right, it could definitely be millions if you got lucky.

That’s fascinating! I didn’t know external mold was a thing, although it makes sense. Thanks for the information
