Yes. It favours the privileged but countries tunes the thresholds for points based on kind of people they want in their country. In the example you mentioned, more educated.

Looking at immigrants I've met, yes, qualifications count for something, but sheer hustle and ambition can play a role as well, and often those propagate into the next generation too.
In hiring decisions, I was told to try to select for potential, not qualifications. Points systems are the classical "select for qualifications" move.
A point system doesn't mean the parameters are well chosen but by it's very definition it's more fair then an interview without any formal requirements.
That potential is usually extremely subjective and unproven.
It’s fair to the country as the country is able to make informed admission decisions weighted by the needs of the country, rather than a take-all-comers model.
It’s fair to the applicants as they have a clear set of guidelines as to what they need to do to become eligible for admission. Need to learn English to boost your score (As in Canada)? Cool. That’s tangible and clear. On the other hand America’s system of, roughly speaking, “Indians need not apply” isn’t exactly fair to the applicants.
Note: a points based migration scheme doesn’t preclude for instance refugee admissions, and Canada’s system has a points escape hatch if a province nominates you based on their specific needs too.
Further, private groups can sponsor refugees as well (pledging to support them):

At least you have some agency in qualifying if there is a clear points based merit system around education.
Less so if it’s things you can’t control (country of origin, ethnicity, etc.)
Everyone knows the rules coming in:
