That’s actually called the “gambler’s fallacy”.
As a side note, I noticed it only now due to skipping, as said above, posts by… hmm… let’s say those with the Tamsin avatar 
— and your quoting it.
However, Blizzard has been known to introduce so-called pseudorandom numbers instead of ‘truly’ (as far as possible with a computer) random ones exactly with the purpose of making this fallacy a fact instead. See, for example: Matchmaking does NOT seem Random to me (with explanation) - #13 by SparkyElf-2852 (the end of the post) or https://us.forums.blizzard.com/en/hearthstone/search?q=pseudorandom%20%40SparkyElf-2852. The key reference is this:

I think some dubious games have been ripping the idea off with ‘karmic dice’ and such, by the way.
Anyway, this is a typical example of rigged ‘rng’.
