That's something of a confusing statement...

All recording formats are "lossy" in that the recording is never a
perfect copy of the original real-world event. A "perfect" recording
of a real-world event cannot exist. But this isn't what the word
usually means in this context.

There is a set of recording formats, such that conversion of a
file into/out of the format gives a result identical with the
original; the chances of it being different are about the same as
those of the very large number of monkeys writing Hamlet. These are
"lossless" formats, such as wav and flac.

There is another set of recording formats, such that conversion of a
file into/out of the format gives a result which differs from the
original. These are "lossy" formats, and include mp3, ogg and all
analogue formats.
