If Earth has been around 4B years, do that mean there was a relative shitload of uranium when it formed? And that’s why lead is so common?

Nah just lots of stable lead
You’d still have over 10% of the sample remaining as U-235.
Also, lead was there in some minuscule quantity when the box was sealed, the only thing that’s changing is the proportion between the two.
