Not quite. General surgery is much, much less competitive than dermatology. Also, there are multiple types of surgery residencies, but everything you described is fellowship level differences in dermatology (i.e. after you finish your dermatology residency)
To add some perspective:
The majority of pre-meds won’t even make it through college competitive enough to apply to medical school. Of the ones who do, 55-60% of them won’t get in to a single medical school. Of the ones who make it to medical school, 51% of the people who end up in dermatology residencies come from the top 17% of their medical school class (i.e. members of AOA - http://www.nrmp.org/wp-content/uploads/2014/09/Charting-Outcomes-2014-Final.pdf). In general surgery, only 15% of the residents were in the top 17% of their class.
