What is "Upsampling"? - inSync
https://www.sweetwater.com/insync/upsampling/
Upsampling can also take place inside of DAW systems at various points. For instance, some plug-ins are based on processes that work better at higher sample rates . Part of the plug-in’s software code will include an upsampling process that occurs before the plug-in acts on the signal, and then downsample’s the audio to the sample rate of ...
Upsampling vs. Oversampling for Digital Audio | Audioholics

Upsampling is on the other hand a rate conversion from one rate to another arbitrary rate. Oversampling in the ADC has been around for quite a bit of time, while upsampling of audio that results in a simple rate conversion is relatively newer. The figure below shows an example of oversampling.
HD Upsampled…An Audio Oxymoron – Real HD-Audio
https://www.realhd-audio.com/?p=1244
Upsampling is a process by which a lower specification audio file is converted into a higher specification audio file using sophisticated software or hardware. A standard CD resolution 44.1/16-bit selection is run through a Weiss Saracon software upsampler (or other high quality converter) to produce a 96 kHz/24-bit “HD Upsampled” file.

Upsampling: Take a digital stream that is at one sample-rate and bit-depth and create more slices (higher sample-rate) at a finer bit resolution (more bits = greater bit-depth). This can happen anywhere a designer sees fit to do it.

Like audio cables' sonic quality and such are essentially nonsense claims (aside from the realm of IEM's for instance or gear with impedences that will cause a FR to shift heavily with odd cables that have like 9 ohms as some folks have spoke about).. But with upsampling, it doesn't make sense to me even from a marketing perspective.
Upsampling or Oversampling? | Stereophile.com

Ayre Acoustics' main man was talking about "upsampling," whereby conventional "Red Book" CD data, sampled at 44.1kHz, are converted to a datastream with a higher sample rate. (Because of its association with DVD-Audio, 96kHz is often chosen as the new rate.)

HQPlayer in particular is very robust in this regard. In essence, one is using the greater computational power of a computer to run more accurate/intensive upsampling whilst reducing the on chip noise created by that process in a DAC. There are many things in audio that might be considered woo woo. YMMV, but this is demonstrably real.
Audio Super Resolution - GitHub Pages

Audio Super Resolution with Neural Networks. We train neural networks to impute new time-domain samples in an audio signal; this is similar to the image super-resolution problem, where individual audio samples are analogous to pixels. For example, in the adjacent figure, we observe the blue audio samples, and we want to "fill-in" the white ...

Audio super-resolution aims to reconstruct a high-resolution audio waveform given a lower-resolution waveform as input. There are several potential applications for this type of upsampling in such areas as streaming audio and audio restoration. A non-deep-learning solution is to use a database of audio clips to fill in the missing frequencies ...
