This isn’t usually the cause. If the cable isn’t inserting fully then yes it can be dust and that often helps the problem, but the retention mechanism itself wears out over time leading to the cable slipping out easily and depending on the design things can get wobbly. I work with electronics for a living and with laptops more often than not it’s the latter category with dust not being too common of an issue since they aren’t kept in pockets. Phones on the other hand it’s usually dust, but I don’t interact with many USB C phones old enough for wear to be an issue.
