Oxford dictionary:

privilege - a special right or advantage that a particular person or group of people has

1st example there: Education should be a universal right and not a privilege.

Globally, it's a privilege. Worldwide many girls can not get it. Or poor.

Even clean water is a privilege on a global scale. Perhaps in USA as well, ehm see Flint.

Language evolves. It's 21st century, privilege isn't about feudal taxes anymore. Queue meant tail and gay happy.

Privilege is bad. It's something we, as society, should strive to eliminate. When you say education is a privilege, what is the message there?

I understand that the OP, and you, are trying to convey a message of this type: I should be thankful that I get X, not everyone in the world gets X, and I will try to remind myself that X should not be taken for granted. Where X is education, but it can also be clean water, or maybe just the right to live, or the right to not go to a reeducation camp if you criticize the "dear leader".

I subscribe to that type of thinking.

I just don't think that using the word "privilege" is the best way to express this idea.
