Display resolution(1920x1080).

You're not going to add any new information, if that's what you're asking. But supposedly YT can be tricked into allowing a higher bitrate per pixel if you scale it up. I personally haven't seen the need though. Just standardize on your native screen size, all the way through.

It makes no sense to upscale a video, then upload the bloated video, because it doesn't contain more information. It just gets blurred.
Every time I see a high resolution video on Youtube I'm happy, because I have a 2560x1440 monitor and expect to enjoy a crisp and clear video, then get disappointed if I realize that the video is still blurry and the resolution isn't the real resolution of the video.
Such video actually wastes my time, because I try and try and try to make Youtube send that (non existant) higher resolution - just to realize in the end it doesn't get sharper because it's not sharper in the first place. I don't subscribe to such feeds because of this.

I record video in 1920x1080, however with bitrate not 8000-20000kbps for example, but in 90000kbps. And then video with bitrate in 90000kbps, but in 1920x1080 resolution I make the resolution in 4k. So, is there any sense in it at all? If the original video resolution is 1920x1080 with a bitrate of 90000kbps, to then just make the resolution in 4k and upload to YouTube. I made the bitrate under 4k, however with a resolution of 1920x1080. In general, everything is done in order to improve the quality of the picture in YouTube, by such manipulations.
Or is there no sense in it? Is it like putting a race car engine into some normal car?
Nope. Bitrate has nothing to do with it.
Imagine a grid of pixels, with few enough and large enough dots that you can see them. Each dot is filled with exactly one solid color. That's all the information you have. Now, split each dot into four smaller dots, two high and two wide. Using only the information that you had just before the split, what color should each of the new dots be?
THAT is upscaling. The one from 1920x1080 to 3840x2160 (actual size of "4k") is exactly like my example, but the math can be generalized to non-integer scaling as well. Regardless, you cannot actually add any more information. The higher resolution is simply more redundant than the lower one.

When uploading to YouTube, it's not necessarily about whether your upload has redundant data or not, or wastes file size.
It's about whether the output from YouTube's processes is good enough or not.
YouTube doesn't save 1080p videos at a very high quality.
That is, they are encode everything, and the quality of 1080p videos are not preserved, leading to a prevalence of encouraging artefacts, which may be more or less visible under different circumstances.
Uploading at 4k, even if it's just a nearest neighbour upscale using 4 pixels per pixel, YouTube treats it as a higher quality video, and even at 1080p output, it looks better, with far less crush, and far less susceptible to noise in the image maxing out the bitrate.
