ZP Black Market achievement

This is my second post, and I'm still not even sure if I'm posting these in the correct places, but here goes.

In the system achievements there are achievements to increase your luck in the Black Market after buying a certain amount of ZP crates, now I understand it increases your luck and chances of winning, but will this luck effect also help with GP crates? If so, what are the percentages or statistics (if any) on how these help.

Like, before getting the achievement, first level of achievement and so on.

Edit: If there is anything else important I should know or missed about that would be helpful.
