Need your help and opinion about this noise (possibly steering pump?)

Recently bought used Mazda 3 2009 SP25 (formal version: 3 SP25 2.5mpi BL10L1 Semi Auto 5gr (Rel. Apr.) fwd 122kW).

I hear whining noise when I turn on the car and disengage the parking brake. The noise changes its tone when I move steering in either direction and if I lock the steering on either side fully, whine changes in to heavy scream.

I recorded a small video of it if you have some time: https://youtu.be/HOcW9ZrgRhY

Does this require immediate attention and am I looking at expensive repair bill?

Thanks a lot.
