Professional grade (or commercial grade) is a term to distinguish from general use or consumer grade products. It is intended to communicate a more durable product with the expectation that it will work better or longer in an environment where it is used more regularly.

I do not believe the term is not a legally regulated and can be used simply as marketing but the meaning is still the same whether it is used appropriately or not.

Primarily, consider the vendor. If you are buying from a general consumer store, it may indicate a slightly more durable product or a marketing ploy. If you are at a trade store or commercial vendor that caters to professionals, the term will likely be more accurately used.
