I'm having trouble following your questions because you're writing in some kind of African patois. Write quality questions, get quality answers.
I think the answer you're looking for is that GDPR (2018 EU data regulations) covers personal data which from the horse's mouth:
>'personal data' means any information relating to an identified or identifiable natural person ('data subject'); an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person; http://www.privacy-regulation.eu/en/article-4-definitions-GDPR.htm
Data which is sufficiently anonymised is excluded which, given algorithms aren't tracking persons but behavioural correlation, means that data controllers don't feel obligated to explain to you how their recommendations work. So for example if you own one of those automated assistants there is significant control over the information they have to share with you as they anonymise the data.
This gets more complicated as youtube algorithms are further protected because:
1) Trade secret
2) Youtube doesn't know for sure either (interesting video: https://www.youtube.com/watch?v=BSpAWkQLlgM
Note: It is even more
complicated because this is new law that is still being defined. There are a number of cases still ongoing against google and facebook under these regulations so it will be up to the courts to decide over the next few years. The wider reason for this ambiguity being that the EU is largely concerned with protecting aspects of extremely personal information (health, trade union membership etc.) from uses that could seriously impact your future i.e. everything China is currently doing with data.

They pay a fine capped at 20mil and may be subject to trading bans. Compensation to individuals is subject to harm caused by the breach which must be proven.
