Is that a net position? I am not interested enough in the further details to try to figure it out for myself, but his net position is more important than the total debt.
He has had recent trouble selling his properties for the asking price. He put up Trump International (the DC hotel) on the market in Oct. 2019 for $500M. There were no buyers at that price before he took it off the market due to covid-19.
There is no indication that he has the resources to finance the debt. Nor is there indication that he does not have those resources. We simply do not know either way until a better picture of his finances comes out.
