strongly disagree.
In fact high winning probability plus high payout basically defines edge
If you dabble with probabilities given by options delta then your calc is off.
I agree with MM. Also it silly to talk about "a trade". Talk about a set of 50 trades and 50 sets of 50 trades, then it gets meaningful. Single trades are noise. So get an edge over 100's of trades. That is what you want, not a single trade with an edge.
