Betsy's classmates voted her "Most Likely to Succeed".Titles and honorifics are usually capitalized, like President of the United States. Now it's usage is a bit broader to refer to the phenomenon of Yearbook honorifics or high-acheiving students.
Of all his classmates, Mark is most likely to succeed at schoolwoork.It's not capitalized because it's just a phrase, not a title.
In this book, people are usually voted in different categories, Most Likely To Succeed being one of them. Best Dressed, Biggest Flirt being others.
There are jokes based on this concept. Such as: She was voted Most Likely to Get an STD.
