Only if they are compressed. ZIP files can contain data that is
stored (uncompressed) or compressed by a variety of methods.
 
Eg:
=>*zipex pdptube/zip
Name       LoadAddr ExecAddr Le ...       CSize  T
!Boot      FFFFEB4D B89DE0D1 00 ... B499E 000174 8
!Run       FFFFEB4D 9FAB139F 00 ... 88FEB 00006F 8 <- compressed
!Sprites   FFFFF94D B89DE937 00 ... F1F90 000153 8
!Sprites22 FFFFF94D B89DEE79 00 ... 71A39 000239 8
!Sprites23 FFFFF94D B89DF408 00 ... 2082C 0001DD 8
X          FFFFFC4B F0F9999A 00 ... 5EC91 000031 0 <- uncompressed
!Help      FFFFFF4E 2AB6B8FA 00 ... 28663 00011C 8
PDP11Em    FFFFFB4E 2AB5B712 00 ... 70120 002C93 8
PDPTubeDoc FFFFFF4E 2AB69034 00 ... 3ACF2 0002E7 8
 
And there's nothing to stop you compressing a ZIP file:
 
=>*zipex update/zip
Name       LoadAddr ExecAddr Le ...       CSize  T
Docs/zip   FFFDDC4D B89F34F1 00 ... 83653 017638 8
