The mental aspect is the only thing that can throw off the gamblers fallacy aspect of it. An inanimate object (dice) is not deciding things here so if the players think they cant win they wont. But stats over 80+ years do show that 3-0 ends in 4 games 65%+ of the time so that does support things. Once the mental aspect of "oh **** we're done" is conquered the odds swing hard towards a possibility of a comeback.
Winning 4 games in a row in hockey is hard regardless of anything in any case though due to just random bounces and reffing so it's not like I'd be betting on the Rangers in any case at this point.
The number is 62.8%, not 65+. 110 of 177 teams have completed the sweep. And, again, it's not so much a "gambler's fallacy" thing as my belief that all series results only fall into win or loss categories, no matter how many games they were accomplished in.
