The shuffle button does it’s thing every time you activate it. I believe, anecdotally, that it uses whatever song is playing or selected as a seed to build the random queue.
Try this, select a song and press Shuffle. When it gets to a song you don’t want to hear, skip to a song you want to hear and toggle Shuffle off and on.
Technically right. Computer can’t do actually random calculations, instead researchers have made pseudo random functions, which similarly behaves as a truly random function would.
I don’t know where you heard that but it’s not correct.

I didn’t hear it anywhere, its personal experience. Spotify straight up isn’t shuffling any of my older liked music. Everytime I hit shuffle it always ends up localized around recently saved music and it never changes. Moreover, that’s a blogpost from a decade ago. Spotify changes stuff constantly. I seriously doubt that is the same algorithm they’re using now. ESPECIALLY considering they’ve introduced ‘Smart Shuffle’ which doesn’t only shuffle music you have saved but adds completely new music into the mix as well. That and Spotifys overall quality control has dropped drastically in the past decade.
I use Virtual Shuffle to force Spotify to play truly random tracks https://shuffle.virock.org
