Ratio of colors to produce white in color television
No, you are interpreting it the opposite way. Those are the (approximate and really old) ratios for combining RGB signals to make a greyscale signal, or brightness value. So as you can see, eyes are most sensitive to green so it contributes the most to the brightness signal, and least sensitive to blue so it makes least contribution to brightness signal.
The reference white point is D65 (6500K) and when you split a greyscale signal into RGB components, you get equal RGB values. 100% white is 100% R, 100% G and 100% B.
And to convert RGB to white, the 100% RGB adds up to 100% white, as 30%+59%+11%=100%.
