The South Americans continue their campaign this evening when they face hosts Brazil for a place in the quarter-finals.
When asked if the current crop of players are similar to the squad that he was part of at the 1998 World Cup, Zamorano told FIFA.com: "No, the current generation has broken the mould. Chile have always had good players, but an entire generation of them is hard to come by.
"These guys have a different mentality. When you hear them talk, they all speak about becoming world champions. While two or three of us had played abroad in the 1998 squad, now 95% of the players have done so.
"This team are better equipped to take on different international challenges: they have earned their stripes and are a lot more mature and experienced."
Chile's previous best appearance at the World Cup was a third-placed finish in 1962.
