With Youtube being rather wonky for me at the moment, I'll point you to someone who is practically the best at these multiple titles comparison:
Hardware Unboxed testing 30 games done with R5 1400 stock + 8GB 2666 DDR4 which would be closer to your system:

Video start time tag were manually added, so if it didn't work then just fast forward to 13:30.
I did give the video you linked a quick look and in my opinion it was not representative of the settings you'd be using on these card. Take the Deus Ex result for example: the NJ video test with 16GB of DDR4 2400 and the G4560 on that game at High settings resulting in both card dip below 30fps (35avg/26min for the RX560 vs 30/24 for the GTX 1050).
And I don't think you'll actually game at those settings justify the framerates win for the RX560 vs the HardwareUnboxed test with Medium Settings which produces the same 41avg/33min fps on both cards.
Again, Watch Dogs 2, 1080p, NJ High settings: 37/25 vs 32/21 in favor of the RX560. When HU Medium settings: 55/50 vs 51/42 in favor of the GTX1050.
Not to mention the weird thing like Rise of Tomb Raider result with HU video with both on DX12 Medium SMAA, 47/32 GTX1050 vs 47/35 RX560, yet the NJ video shows Very High settings, DX11 GTX1050 48/35 vs DX12 57/36.
