No.  Definitively not.  mke2fs -c also runs badblocks(8),
which tries to read every single byte in the partition.
(Optionally you can even have it do a write test.  There is
even a non-destructive write test in newer badblocks.  Use with
care and do have current backups.)

fsck just checks that the metadata (directories, space used
by files, etc) looks OK.
