I agree with your interpretation.
As I've mentioned before, I have sometimes wondered if Georgiana's 'fortune' might have been given her as part of her mother's marriage settlement. I have read of settlement documents in which the income from the money was given to the husband during his lifetime, and but then the principal was to be equally divided among the younger children (with all the usual verbiage in case there were no younger children or any children at all, etc.). I think less likely than not in the case of Lady Anne, as the late Mr Darcy was certainly rich enough to take care of his wife, and so the money would probably be added to the estate with provisions for her welfare if he died first.
Also, if the money came to Georgiana via the marriage settlement, Wickham might be less likely to know how much it was, and Darcy's letter implies - to me at least - that he did know. I suppose the difference in his knowledge hinges on Wickham being privy to the contents of Mr Darcy's will. Certainly Mr Darcy might have told him, but if he did, he might well have told him about anything else, so I don't see the probabilities changing based on that. I have no idea if all the beneficiaries get to hear the will being read in anything other than movies which need to move the plot along. If that was actually something people did, then I think it moves the needle further in the direction of "Georgiana's fortune came via her father's will".
I wonder what Jane Austen would think about so many people obsessing over details of her books. I hope she would at least be amused.
