One in 2.4 million means you are unambiguously uniquely identified out of 2.4 million clients, which is the exact opposite of untraceable. If your browser fingerprint was similar to 2.4 million other browser fingerprints, then you would be untraceable.
1 in 2.4m is being similar to ~150 other Americans. Not good odds for hiding among the crowd once non-client browser specific identifying clues are taken into account, such as browsing habits. 1 in 2.4m is being similar to ~400 other facebook users, and facebook knows a lot more about its users than just the client browser fingerprint.
