No one knows the future. ~5 years ago anyone with a pulse could match obgyn, pm&r, gas, psych. Then out of the blue there’s just a nasty match one year in one those fields. You can try to guess based on match outcomes, but it’s all just that—a guess. The only constants are that peds and FM are under paid/non competitive and derm and surgical subs are impossible for most people.
The only definite is that if you reapply and fail to get in MD you will have wasted a year of physician income and, assuming you can obtain a DO acceptance elsewhere, will have even more competition bc more schools will probably open up.
Also, turning down this acceptance will likely blackball you from the cheapest DO school so getting an acceptance to another DO school if you fail to get in MD will also result in more debt on top of lost earnings.
Unless you can pump out an above average for MD mcat between now and the start of classes and have an otherwise solid app, I wouldn’t chance it personally.
