I don't know what his personal beliefs are on Theology, nor do I find it important. He was asked if he believed in evolution in an interview, and gave an answer that he believed that the Universe has a creator.
If you find that confusing, it's not uncommon. In brief, there is a Philosophical question dating back to the origins of writing. "Does the Universe require a creator or can it spontaneously just happen?". Contrary to what some people claim, the question has not been solved nor can it be solved any time in the foreseeable future. What we could state with a degree of honestly is that all of the arguments both for and against having a creator have been made, so read the work done on both sides and contemplate your own answer.
Answering that question does not require any Theology, or belief in a specific deity. It's not an easy question to contemplate, namely because we are full of taught biases. You won't get the concepts of the debate in a few minute post.
Believing in a creator does not mean you believe in a particular Theology. Atheists tend to falsely lump both concepts together and use them as an ad hominem when it suits them. To be fair, theists do the same thing in the other direction.
That said, if someone does believe in a creator then there are certain aspects of most theologies that become important. If you have done the ground work to believe in a creator, generally you will do the same amount of ground work in determining which portions of theologies may also be valid.
