Defining the limits within the namespace creation doesn't help. Seems the Operator is trying to set itself up with unlimited resources and that goes against the limits defined in the default.
Pods "awx-operator-controller-manager-59878d899d-kdjqg" is forbidden: exceeded quota: default-f5vnz, requested: limits.cpu=2,limits.memory=8000Mi,requests.cpu=500m,requests.memory=4000Mi, used: limits.cpu=0,limits.memory=0,requests.cpu=0,requests.memory=0, limited: limits.cpu=0,limits.memory=0,requests.cpu=0,requests.memory=0; Deployment does not have minimum availability.
So I do need to adjust the limits it would seem for the Operator itself.
