Only in a "does-flying-an-aircraft-in-a-flight-sim-count-as-really-flying?" kind of way.
There is no substitute for the feel of a properly weighted cue in your hand as you carefully work out the angles of a beautifully executed shot in your head before making it happen on the felt-covered field before you. Pool sims teach you nothing about overcoming the hazards of dead bumpers, threadbare patches on felt, un-level tables, and crappy, corkscrew-shaped house pool cues. Real pool players overcome these difficulties with ease, and the best pool players use them to their advantage.
