(Contrast with printf '%s\0' *ABC* | xargs -0 ls -l, which avoids that limit by splitting into multiple ls invocations if there are more names than just one can handle).

It's important to distinguish that in the *ABC* case, the list of filenames is generated by the shell before ls is even started. This implies some limits not present in the ls | grep case -- the local platform's maximum command-line length is pertinent.
