I'm a little stuck... Click here to teach me more about this clue!

'is risk' is the definition.
(I've seen this before)

I don't understand how the remainder of the clue works.

(Other definitions for chance that I've seen before include "Run a risk" , "Possibility - opportunity" , "I wish (but it won't happen!)" , "part of Monopoly" , "The unpredictable element of existence" .)

I've seen this clue in The Sun.
