Wrong. This is a misnomer from the past which still rears its ugly head occasionally.
Most modern rimfires have forward-stops which stop the overtravel of the firing pin, which restricts it from actually hitting the breech, which is why very-old rimfires could eventually deform the breech face or break a firing pin upon too much dry fire. While there are some modern rimfires that should not be frequently dry-fired, they are few and far between.
The Marlin Model 60 - being relative to this thread - features such a stop, and dry-fire will cause no harm as the firing pin still has a slight clearance before contacting the breech.
