No, if a sample size of monthly salaries is: $1k, $3k, $4k, $10k, $12k
The median is $4k. Achieving better than that may indeed be a slim chance if it represents a level up in seniority. Your background and skills matter.
Also, in this sample size, only 40% are above median. If you measure everyone salary to the dollar, it will approach 50% but never get there. In fact above median will always be < 50% by definition.
