Unless you were in the apex male top 5% at the college, that just sounds nuts.
Women may meet a lot of men regardless of dating apps, but everyone wants a bigger better deal. Dating apps provide access to many people, such that a better quality mate is possible. Again, you may be flawed by being in university.
In the real world you meet a far wider range of people in demographic, socioeconomic status, age, education, etc. So the people you meet that may match what you want is drastically lower that university, which will generally function as a filter for socioeconomic status, demographic, location, and especially intelligence. At a technical college, it even preselects for area of interest.
