Sets can spawn and drop as much as they want. Uniques can only be generated one time in a game. This includes gambling. If the item is generated on the gamble screen and you don't buy it, then you can't get it again that game.
But since the sickle is a set item, it doesn't matter as the constraint doesn't and never has applied to sets.
edit: Wow, I can't type today, lots of typos.

It's all just zeroes and ones and duct tape in the end.
