Some polling places were closed, forcing those people to vote elsewhere. Not everyone can wait in long lines for hours. There were disinformation campaigns about vote by mail and many people were worried those votes wouldn't be counted because of it. I don't know if I heard confirmation it occurred on election day, but I read news stories about voter intimidation because of groups of armed men. They employed tons of tactics to suppress voting.
If you suppress everyone who disagrees with you from voting, of course you're going to win the popular vote.
Did he technically win the popular vote and the general election, yes, it appears he did, but 51% or more of people who could have voted did not support this shit. Not to mention he lied. He lied. Yes, he said he'd do some of this, but he also said he'd bring down the price of groceries, make better health care, and make America great again (firing thousands of government employees who did nothing wrong is not making anything great). He has no intention of bringing down grocery prices or fixing health care. He's getting rid of competent people and replacing them with loyalists.
It's difficult. You don't work, you may not be able to feed your family. They're already detaining immigrants, and who knows what they'll do with political enemies. The riots are coming, but I suspect they won't come until the screws are tightened more. I heard there are going to be protests at every state capital this week. That's something.
