Is it important for relatives of Canadian immigrants to apply for a visa to study in Canada?

I know a case. Parents immigrated to Canada with their children and family. Later, the child returned to China to develop and gave up his permanent resident status in Canada. At this time, my parents were still living in Canada. Later, although the children developed well in China, they still wanted to go to Canada to receive a higher level of education. As a result, the child's application for studying abroad was successfully signed. Through this case, you will know whether it has any influence. None of your relatives is closer than your parents.
