Not necessarily. I am in the same case as OP. Basically I am a specialist with a PhD in a niche topic. There are at most a handful job postings per year that fit my profile perfectly, but then I have virtually no competition. If you have a generic profile ("frontend developer"), you get hundreds of opportunities per day, but are alao in competition with hundreds of similar applicants. My position is comfortable, but if interest in my particular combination of skills decreases, things could get quite difficult.
