Your first pattern does not match the entire string, and field matching parts are
[^ ]*, that is, any 0+ chars other than a space, so the last field cannot be matched (it contains spaces).

\S+ patterns matching 1 or more chars other than whitespace, and the last one does not match the last field.

See the regex demo
[^\t]* matches any field in a tab-delimited text since it matches zero or more chars other than a tab.
