Points out nothing is gained (3)
I believe the answer is:
won
'is gained' is the definition.
(I've seen this before)
'points out nothing' is the wordplay.
'points' becomes 'wn' (**).
'out' means one lot of letters goes inside another.
'nothing' becomes 'o' (looks like zero - 0).
'wn' going around 'o' is 'WON'.
(Other definitions for won that I've seen before include "Eastern currency" , "Korean currency, was victorious" , "Gained a victory" , "prevailed" , "Triumphed" .)
