CentOS 7:
$ cat /etc/group
wheel:x:10:a,b
However I do not see any user with gid=10 when I do
cat /etc/passwd
Is this some special id?

This is telling you that users a and b are members of the wheel group.
These are secondary memberships; the primary group is listed in /etc/passwd as part of the user record.
In this particular situation, where wheel is a group that confers special treatment, it's unlikely there will be any user with it as their primary group. So you shouldn't expect to find group 10 in /etc/passwd.

uid = 10 for wheel group
Incorrect. That number 10 is the group ID of the wheel group. It is not a user ID at all. There's no reason to think that a user ID of 10 is relevant to that record in the groups table. Certainly the number 10 in the group ID field does not indicate that. There is no mandatory correspondence between user IDs and group IDs. Groups are linked to users by their account names, as you can see, and by the primary group ID in the password table.
