So are all of the rgb lights in a pixel always on and the rgb values of a pixel just determine how bright the rgb led lights are relative to each other?

When an image is displayed on the screen, the RGB LEDs are not necessarily always on; they turn on and off rapidly or change intensity to match the required color for each pixel to display the image correctly. This process happens so fast that the human eye perceives a stable image.

notice there are twice as many green LEDs as blue or red.

Are the green LEDs smaller to make up for the fact that there are more of them?

In a sense, yeah. iirc this is a pentile oled layout, which is moreorless the defacto led layout on oleds. This is partially due to manufacturing costs (an RGB/RGBW pixel layout is much more complicated to produce and can't be scaled down).

This is a bit more physics-y than perhaps necessary, but an overview of OLEDs: https://www.explainthatstuff.com/how-oleds-and-leps-work.html
It also contains a comparison with LCDs if anyone's interested.
