Hell, if nothing else, the fact they have the Commanders left says that's very unlikely.
On top of that, they haven't had that kind of negative run since 2015, and then only after losing the QB. And then there is the fact that other than 2015 they have been a pretty successful regular season team the last 5 years. And then, there is the fact we have one of the top offenses in the NFL. And then there is the fact we play 3 of those last 5 games at home. And then there is the fact we have already shown we can beat the Eagles. Then there is the fact the Bears aren't a particularly strong team. Then, there is the fact that the Bills are winning by narrow margins, even against bad teams.
In all, there is nothing so impressive about the schedule, or so unsettling about the Cowboys that there should be any realistic concern about finishing the season 0-5.
