Hi,

Is there any definition for the word "privileged user" in the Linux (especially RedHat) environment?

IMHO "privileged" vs "unprivileged" is really a relative thing in that the privileged user has more privileges than an unprivileged user.
Simply saying a user account is "privileged" doesn't convey what those privileges are.
Often, those privileges are the ability to gain root access via some means like su, sudo, doas, run0, capabilities, etc.  How many of those privileges are granted becomes difficult to say.
There is also the for something like a DBA to log in with their unprivileged individual account and gain the privileges of the user that the database runs as.  Similarly, it's possible for a backup & recovery administrator to log in with their unprivileged individual account and gain the privileges of the user the backup daemon runs as which isn't always root.

I am currently learning RedHat OpenShift and the courses include a question where the answer is that 2 containers run with UID 27 are called privileged. (DO190 ch03s08 if you have access).

Some systems have configurations where a UID or GID below a specific value is considered privileged for some thing.  But that's a subsystem / daemon configuration.

I am aware that it is common that normal (real people) users start with 1000 ongoing, server process users are below. Is there a difference on the IDs or is that just tradition?

I've seen 100, 250, 500, and 1000.  The exact number is a convention and more or less common depending on the time and the family of the distro in question.
