Of course, if someone really wants to be a doctor and they work hard at it, i’m sure they will eventually get into med school, if they don’t care what kind of med school they get into i.e. university of las vegas med school

Medical schools don’t look at high school grades.

And if your grades are good but not good enough, they are not going to “eventually” get you into medical school–it only gets harder year after year. If a person isn’t qualified for medical school, they’re not going to get in.

It’s also a very grueling process to apply to medical school. It’s not a matter of “just applying.” It’s very expensive and time-consuming. It can cost in the thousands of dollars, if the applicant is applying to several schools. There are numerous “rounds” to applying, including visiting the schools, interviewing, and filling out lengthy applications.

Yes, some people do apply more than once (though usually not over and over again), and do get in. But they’ve probably changed their game plan–applying to different schools, retaking their MCATs (which in itself is expensive and time-consuming), and perhaps taken extra undergraduate courses to prepare themselves. That’s not an option for everyone, and many people would prefer to move on with their lives and enter another field.
