I think there's a misunderstanding here. Will OpenGl be able to run games that were coded in DX? No. Vulkan's existence means I don't need DX12, and I don't need Windows 10, because game devs that care about me (and my 35% brethren) will have a Vulkan port, in the same way that game devs that care about any other non-Windows platforms have an OpenGL port (or are already using an engine that does the porting for them). Technically you're right that Vulkan won't help me run a game that uses only DX12, I doubt there will be many of those games though because of many bad incentives to do that.
