as far as I know its less then that amount most of the time.

a port can either have (as far as I know, if I am wrong expect ignition to correct me) 4 x4.5mbit or 4x 9mbit on legacy (docsis), so 18mbit or 36mbit, it is not always 36mbit. In my area it is 18mbit, and it can even be a mix of 4.5 and 9mbit channels.
On overlay (docsis3) it will typically be a single 9mbit channel for non uplifted areas and 18mbit for uplifted areas, I think seph has even mentioned some overlay areas even only have 4.5mbit.

so basically a chance of 36mbit going to the cabinet if on legacy. Which is only 10mbit and older 20mbit users. I also think its multiple cabinets per node, so one cabinet wouldnt get that bandwidth to it self.
