Note they say "roughly" the NYT has no idea either how much it cost either.
Between shooting 3x and marketing over $400 million easy. Hell they were still cutting the movie a few weeks before release!
Solo was over $275 million, without marketing.
TROS is performing worse than TLJ, it is going to struggle to beat TLJ's 1.3 billion haul and it cost more to make than TLJ.
Making the billion dollar mark is going to be a tough slog.
FYI the NYT article references a story from WSJ 2017, there is no evidence it applies to TROS in regards to ticket percentages.

Edit: On reflection Disney might do ok, it depends on how well the movie does word of mouth and how badly the fans were alienated by TLJ. I'm in the camp of not giving Disney another dime so have a built in bias from that point of view.
Still the current numbers don't support TROS being a raging success, it is tracking worse than TLJ and cost more to make. Disney might be satisfied with moving ahead with that and putting the whole fiasco behind them and focusing on Star Wars streaming as I speculated the other day.
