It's not even 52%, in the end it's ended up being 50% VS 48.3%. He barely got half of all votes with the overall gap only being 2.6 million votes. That's razor thin, the only reason it worked out the way it did (apparent "easy win") is because of the electoral college system, which is a bit biased towards conservatism anyway by giving quite a bit of power to smaller, less populated states.

Besides that, I do agree that it's a bit of a question what will happen. I've seen people say that Rubio and Waltz appear to indicate a slightly different course but no one really knows besides the coming government.
