Border crossings don't even account for a majority of the people joining the unauthorized population in a given year. In fiscal 2016, for instance, the Department of Homeland Security estimated 628,799 people who had previously entered the country legally overstayed their visa that year. Other groups, such as the Center for Migration Studies, have similarly estimated that visa overstays account for about two-thirds of the total number of people joining the undocumented population in any given year.

Ive stated all along that the system is terrible, it has not been fixed or changed. They are not good at tracking those that leave.
Now something that you are totally ignoring. Those that came here legally, have been screened vs those that cross illegally.

Currently, most non-immigrant arrivals, i.e. foreign nationals admitted with a visa for a temporary stay, are asked to fill out a form known as an I-94 Arrival-Departure Record when they enter the country. The top half of the form is given to the immigration inspector who allows the person into the country and the bottom half is supposed to be collected on departure. A 2003 report by the U.S. Government Accountability Office (GAO) found “there is no accurate list of overstays” because not all departure forms are collected and not all can be matched to arrival forms.4 In 2001, according to the GAO, 20% of I-94 arrival records had no matching departure record. Mexicans and Canadians entering the country with Border Crossing Cards are not required to complete an I-94 unless they are requesting an extended stay. In effect, the government has a pretty good idea of how many people come into the country if they fill out one of the forms, but it does not have a full count of how many leave.

Estimating Border Crossing Card Overstays

Unfortunately, there is little hard data on which to base estimates of the number of unauthorized migrants who entered the country by using a Border Crossing Card. But, given that the traffic is so enormous—as noted above, an estimated 148 million entries in 2004—if even a minuscule share of these individuals overstayed, they would contribute significantly to the unauthorized population.

Cardholders can easily overstay their visits since, unlike with I-94 forms, there is no attempt to check on whether the border crossers leave. Moreover, border crossing cards have been used fraudulently by others to cross because the biometric identifiers are not checked for all border crossers or at all ports of entry. The Center estimates that 1.7% of Mexicans entering the country each year on nonimmigrant visas become unauthorized overstayers, based on Warren’s data. Assuming that the rate of overstays for Mexicans holding Border Crossing Cards is similar and that this population has built up over time, produces an estimate of 250,000 to 500,000 cardholders who have become part of the unauthorized migrant population.
