Short answer: No.
6000 x 4000 pixels correspond to an aspect ratio of 3: 2.
1920 x 1080 pixels correspond to an aspect ratio of 16: 9.
The number of pixels of a typical 24-MP sensor used to create an HD image is not all 24 MB. Even if the width is "uncropped", only 3375 out of the 4000 horizontal lines are used. That's a total of 20.25 MP.
"Raw" vs. RGB
Say, "red" ("R"), "green" ("G") and "blue" ("B") are the colors on which the filters in a Bayer mask are centered and most permeable.
Let's label the light frequencies used in RGB color rendering systems with R, G, and B.
Raw image data is monochrome, but each "pixel" does not collect exclusively "red", "green" or "blue" light. Each filter passes a wide range of frequencies with a peak at a particular "color". There are many overlaps between each color filter, especially between the green and red filters. All three R, G and B values are interpolated. "Red" filters in a typical Bayer mask are centered at about 590 nm, which is more yellow-orange than red. The red channel in RGB is about 640nm. The Bayer mask filters are also not centered on the G and B frequencies used in RGB.
The R, G and B values for each pixel must all be interpolated from the raw values of the sensors covered with "R", "G" and "B" filters, since "R" ≠ R, "G" ≠ G, and "B" ≠ B.
Each of the filters in a Bayer mask transmits a wide range of wavelengths. They are attenuated for peak transmission at about 455 nm ("blue"), 540 nm (green) and 590-600 nm ("red"). There is also a lot of overlap between what passes through each filter compared to the others. Our RGB color rendering systems use values of approximately 480 nm (blue), 525 nm (green), and 640 nm (red) for the three primary colors. Some screens also contain yellow subpixels that emit at around 580 nm. As you can see, the tips of the detectors used in our cameras do not match the colors used in our output devices.

The result of demosaicing / interpolating a 24 MP raw file is usually a 24 MP image with 24,000,000 RGB pixels, not a picture with 12,000,000 G, 6,000,000 R and 6,000,000 B pixels. It's also usually an aspect ratio of 3: 2 (6000 x 4000 pixels) and no aspect ratio of 16: 9.
