Card Game Origin

Often used metaphorically to describe non-physical advantages like information or resources.

Metaphorical Use

It's a casual expression, suitable for everyday conversation rather than formal writing.

Remember, holding all the aces is figurative and doesn't involve real cards.

The phrase is dynamic, meaning the power can shift and someone else might hold all the aces in the future.
