The root cause of this sort of comment is people often equate the outcome of democracy == good or desirable to them or even the majority, which is not necessarily the case. People can whine about the outcome of a democratic process all they want, which even if done perfectly could be a compromise that is distasteful to all parties but still democratic.
You'd normally be right. But the US did just have the richest man in the world setup a lottery to buy votes, and walked it back to "oh it was rigged anyway" when called out on it. Any lawsuits is pennies compared to the results.
It was subtle before with stuff like Gerrymandering that the layman would never notice. But it's so blatant now that the democratic process is compromised.
