Being a '95, it should go in the the 92-99 section, where the people more familiar with that generation look first. The most common cause for low oil pressure is warn crank bearings. You could try running some heavier weight oil, and see if it helps.

Yes, this usually indicates a worn engine, with worn crank bearings. I limped an 99 grand prix along for a couple years using heavier oil like 20W-50, but eventually the car needed a new engine. You could easily be in the same boat, especially if the seller has admitted to some leaks and replacing the oil pump.

Personally, this is one of the things I'd be on the lookout for when testing a used car, and it'* something that would indicate to me a worn engine and large bills in the future for a rebuild or a replacement.

If you've only had it for one day, is there any chance you can return the car for a refund? You're basically risking owning a car that will need a new engine sometime in the future, possibly in the very near future.
