The song you linked has nothing to do with orchestra performance or anything. It lacks the fluctuation of an actual artist performance.
It is music composed and played by a computer at the end of the day.
Compare it to something like https://osu.ppy.sh/s/92795 which fluctuates too much to be represented by a single 60bpm section although it is 60bpm throughout.
An actual instrumental song played turns out as an abomination like https://osu.ppy.sh/b/671988
For an actual orchestra it is not too much different compared to a solo performer as the character of the timing is still determined by one person alone: the conductor.
Also, the point I made still stands: many notes does not equal high bpm.
