maybe the race part is forbidden.
but the requirement said dont want bujang, student uni is not considered sensitive.

last time i seeking for rent, dont know how many time hear dont want bujang people. if you sked this group of people most likely will have problem to pay rent, then ask for longer security deposit la.

Its within the renters right to choose to whom they want to rent it.

Better to tell now rather than later when you want to get the key then suddenly house owner cancel last minute before you sign the contract.

What you did is stupid. The agent is just a middleman, the owner is the one you should complain... 🤦‍♂️
