Scala's in a different league to Kotlin, Clojure, or Apache Groovy. None of those 3 languages are in, say, the TIOBE Top 50 this month, whereas Scala's listed with almost 1% of the share, compared to Java's 12.7%.
For somebody who genuinely prefers Kotlin and has the luxury of being able to be picky, then sure, focus on Kotlin to exclusion. For somebody who just wants a job though, it would probably be better to stick with Good Old Fashioned Java in the near-term and learn Kotlin (or Scala or Groovy or Clojure or whatever) on the side over time.
