Incorrect. In a democracy, the people gather, present ideas, discuss, argue, and eventually reach agreement. That agreement may not be exactly what any individual wants, but the population at large does reach an agreement as to what is in its interest as a whole group.

Whereas in reality the interests don't show up. In fact, in the USA, showing up to the table (a.k.a. lobbying) has come to be considered abhorrent behaviour, even though that's technically the civic duty of all citizens in a democracy. Lobbying (i.e. gathering, presenting ideas, discussing, arguing, and eventually reaching agreement — and passing that result onto the massager, in the case of representative democracy) is the only way a democracy can function, fundamentally.
China isn't cut off from the rest of the world. They notice just as well as we do that even if these places are democratic on paper, the people don't actually practice it, instead leaving control to a small group of figureheads and the few people who do show up to (i.e. the 'evil' lobbyists). Their claim is that leaving control to that small group of people who are pushing their own personal interests, is, on the spectrum, ultimately less democratic than an equally small group that ostensibly takes in all the considerations of the population at large.
I infer that what you are trying to say is that in a place like the USA, the social environment would allow people to change their ways, kick the small group to the curb, and start practicing democracy, if for some reason they wanted to in the future, without tremendous pushback, whereas the CCP would not be so accepting. That is no doubt a fair assessment, but completely talking past the original point. It wasn't said based on some kind of future hypothetical.
