Yup. Even gross abuses of Redshift run fine with appropriate roll ups and caching. At a past job we did it “wrong enough” that it took a while for a more state of the art solution to catch up. This is not to say the abuse of Redshift should have been done, but AWS has been abused a lot and the engineers there have found a lot of optimizations for interesting workloads.

But to pick the wrong DB tool in the first place and bemoan it as “not scalable” is a bit like complaining that S3 made for a poor CDN without looking at how you’re supposed to use it with Cloudfront.
