These numbers are several years out-of-date.
AMCAS has data from the most recent cycle here: https://www.aamc.org/data-reports/students-residents/report/facts
(There is a separate database of undergrads that supply 5 applicants/year. It’s a subscription only database and requires a med school email account to access.)
BTW, the number applicants produced annually includes both current undergrads and alumni applicants. AMCAS only captures the applicant’s baccalaureate-granting institution of record… The alumni may be several years (even decades) out from graduation, may have earned graduate degrees or attended post-bacc programs, may have completed the bulk of their education at one school but received their degree from another—there’s no way to tell.
Also be aware that less than 40% of matriculating med students move directly from undergrad to med school. Most take one or more gap years. And 1 in 6 med school matriculants have been out of undergrad for 4 to 10 years.

RE: HP advisors
I wouldn’t consider easy access to premed advisors necessarily a major plus for an undergrad.
Since there are zero training requirements for health profession advisors, many are truly horrendous and often give spectacularly bad advice. (There 's a recurring theme offered by actual med school adcomms over on SDN: the road to med school is littered with the corpses of students who listened to their pre-med advisors.)
Additionally, very few, if any HP advisors, have much experience with the vast majority of med schools. They may know something about one or two med schools if their school serves as “feeder” to particular med school or if there is med school associated with the undergrad… But med schools outside their locale? Or outside the school(s) the undergrad typically sends students to? Hopeless. The best they can do is point the student at MSAR.
Also HP advisors have no idea what to with non-traditional applicants or students whose journey to medicine has been atypical.
The truth is , even at smaller schools, student get very little guidance beyond generic guidelines: fulfill the pre-reqs, study hard for the MCAT, make sure you have appropriate ECs, make sure you have strong LORs from 2 science and 1 non-science professor. All information readily available on line.
Students don’t receive guidance about what schools to apply or how many.
