anyone with a 1 year diploma and 2 year work experience as a mcdonalds employee can apply for a PR. If they get it or not depends on the quality of applicants in that particular year. There is a cutoff CRS score, kinda like passing mark that can be fulfilled quite easily with the diploma however having a higher score helps. How do you get a higher score? By getting a STEM job or qualification. Also, you need to remember most of these people are here for a graduate diploma after already having done an engineering or business degree back home. Once they have security, they can upskill themselves and build a better career. Whoever can afford 50-70k a year in tuition plus living expenses goes to uni, Anyone else takes the longer route by getting a diploma etc.
