Hi,
Amazon Linux is not compatible with RHEL the way CentOS is and it's not a supported platform for the RPM installation: https://www.pgadmin.org/download/pgadmin-4-rpm/
The repo configuration probably uses some variables to create the download URLs and because the versions don't match, it results in a 404. You may have some luck downloading and installing the RPM directly, but you'll likely want to take a look at other installation methods on the page I linked if you want to install pgAdmin on Amazon Linux.

Trying other mirror.
One of the configured repositories failed (pgadmin4),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=pgAdmin4 ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable pgAdmin4
or
subscription-manager repos --disable=pgAdmin4
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=pgAdmin4.skip_if_unavailable=true
failure: repodata/repomd.xml from pgAdmin4: [Errno 256] No more mirrors to try.
