Does using this https://trailhead.salesforce.com/projects/workshop-platform-events/steps/platform-event-subscribe count towards the limits for cometd clients? I hope not.

I've been migrating our code to use Platform Events instead of Streaming API Events, mainly because we're getting close to the 200K/day limits on Streaming, while PEs offer 100K/hr, BUT, if you use cometd clients (like we do in our VF pages) you are limited to just 25K/day! Events are calculatged as #events X #subscribers, so this really adds up fast.

I know I can purchase additional PEs in 100K/day blocks, but can't seem to find any info if I can similarly purchase additional blocks of Streaming API events. Any help/guidance to docs/info will be appreciated. Thank you.
