For the most part, yes. While balls played on the PGA TOUR often pass additional checks to ensure they’re conforming, nobody is sitting on a secret stash of high-performance Tour-only balls. Ball manufacturers want their Tour staff playing the retail ball and that’s mostly what happens. That said, nearly every manufacturer has a couple of secret menu offerings. These are typical niche balls (very low or very high spin offerings, for example) that won’t be a good fit for most golfers. It's also true that some Tour pros play prior-generations balls that were once the stock retail ball but have been superseded by newer models.
