Why are YouTube videos without ads?

Question

YouTube

Hello. On my YouTube account, when watching a video, there are no ads from the word at all on ANY device, and it doesn’t matter whether it’s a browser or the application itself. At the same time, the premium has NEVER been purchased, I have not done any manipulations and there are no ad blockers (there is advertising on the same video without logging in or on another account). Why is this and how can I do the same on another acc, where there is advertising?

PS: I know about the method with a dot after the domain, but I need it not to be in the application either

Answer 1

An account could be connected as a family account to another, on which the blocking is enabled, in fact, people do just that, they collectively buy premium when they gather in a 'family' and each pay an order of magnitude less.
Xs where to look, according to the mind, it should be shown in the profile .
ps maybe a similar situation, when the account is connected as an employee (linked account) in a business account (brand), maybe someone did some kind of marketing work with the advertiser?
