Was it a really short message? I think you need at least 11 words for 
bayes to be used.
At least that's how I read the following page 
https://rspamd.com/doc/configuration/statistic.html (min_tokens : 
minimum number of words required for statistics processing)

Happy to be corrected - not exactly sure what that option does.
