UK statstics show a 20 factor reduction in hospitalisation rates for vaccinated people vs non vaccinated. However what is not considered in all these statistics is the non-symtomatic cases. If hospitalisation rate is 20 times lower it means also that symtomatic infections are way lower than those detected. In your cited statistics for those 27 cases there would be a lot more not diagnosed at all. The risk here is that although they will pass it without notice they will also risk infecting others-hence the recomandation that vaccinated people still need to use masks. There is a great risk on falling into complancy here if we think vaccination is the silver bullet and is enough.
