No, "limited" means the same thing in the context I used it, there is a limit to how much you can take, the limit being the safe tiles. If you really want to be pedantic, the amount is always "limited" because maps are finite.
The phrase "that you take a limited amount" implies that the amount taken is the primary determining factor. For example, that (at least approximately) taking four tiles is always safe, regardless of which four, and taking four hundred is always unsafe, even if each individual tile could have been one of the aformentioned four safe ones.
But (DF) candy doesn't work like that at all; each tile is either completely safe, or has a noticable (if not always large) chance of having a circus tent behind it, completely independantly of any safe tiles, and only dependant on other unsafe tiles in the minesweeper sense (ie, that you sometimes know there's a circus tent behind either tile A or tile B, but not which).
