No, I don’t believe it does. In particular, Section 4: “How You Can Share the Licensed Technology When It Isn’t Part of a Product” imposes restrictions that contradict the very first clause in the Open-Source definition: “Free Redistribution”.
At a quick glance, I expect the royalty requirements fail the first clause as well, but there’s no point in combing through them for this conversation, given the above.
You obviously want to believe otherwise, though, and I don’t want to argue with you. Feel free to test it in court. Good luck.
You can sell your engine made from unreal and there are no royalties
The license shall not restrict any party from selling or giving away the software as a component of an aggregate software distribution containing programs from several different sources. The license shall not require a royalty or other fee for such sale.
The license does not place any restrictions on this
Open source and free are different
It can be considered open source because you can sell derivative engines (there are no royalties on that btw) and push upstream
Under your source available link the inability to create derivatives is the common theme for what makes it not open source

If someone else comes along, Unreal Engine checks all of those
