There are several companies that can help you to port your Construct projects into console games (all of the XBOX, Playstation and Nintendo consoles).
You can also buy/rent to tools and do it yourself if you want to.
But Scirra and their small team will not develop the exporter themselves.
If creating PS5/Xbox games is what you want to do mainly I think other engines is more suited than C3. But gamemaker will cost you $1500 a year for example. But still, it will require a lot more than a license to be successful on console, and the license fee will not be the hardest part..
