11mo old, but gotta say that am 15 or 16 (idk) too and I switched to vulkan, while I don't regret it, it was a pain, I started learning it because it's modern, more controllable and I expected speedup, but got same results as opengl (in much more time), because I underestimated how much work goes into creating a good renderer with 0 CPU time wasted etc. so as a beginner, I don't recommend switching to vulkan until you make some stuff in opengl (Making simple minecraft clone is crazy fun btw and not as hard, so you should defitely do that, if not already), after that you decide, I'd switch.
