Thumbholes are a nice-to-have feature, not a necessity. They prevent sleeves from riding up when you pull on your jacket, which is convenient, and they add a small amount of wrist warmth for under-glove layering. If you have cold hands or find sleeve ride-up annoying, thumbholes are worth having. If those issues do not bother you, they are not essential. Some models feature hidden thumbholes that are unobtrusive when not in use.
