These arent great analogies because you dont have to have sex with a spy to be a victim of a foreign intelligence operation.

The gambler goes to the casino to gamble. And Alice Huang was sent to meet Jensen Huang under normal business pretenses.

The analogy cant quite represent it but its more like the casino sent a dealer-in-disguise to the gambler on some plausible non-gambling pretenses to spy on him. So he's a victim of the casino's spy operation. Then he gambled.
