>Research shows the UK needs 21,000 more computer science graduates on average, every year, to meet the demands of the digital economy.

This contradicts with most of the Amazon Software engineering jobs in the UK which are targeted to mid-seniors only. Given that this is the case, it is better to hire 1,000 senior engineers to do the work of 21,000 CS grads that need to be trained for the job, which doing that is costly.

The UK just doesn't have the core computer science skills that are needed by FAANG companies. Amazon just bring in engineers from other countries on a work visa just to 'fill in the demand'.
