Basically, an uncancelled show is the same show continuing after being cancelled, a post-script season is similar but after all the plot threads have been wrapped up and a revival is a new series continuing from an older one but updated for modern tastes. According to the trope page, the difference between a revival and reboot is that a revival is set in the same continuity so a series can’t be both. Overtook the Series is only applicable in adaptations, which Dexter’s lab isn’t as far as I’m aware.

Terms used in the real world may be subject to definition drift, the specialty nature of TV Tropes forces us to be a bit more precise. That's partially why we have a disambig page for reboot, while we usually use that in reference to a Continuity Reboot others may see it synonymous with a revival or even a retool.
Revival: They made a new series, didn't need to be canned or anything. They just decided to make more.
Uncancelled: from cancellation to resurrection.
Post Script Season: They got canned and wrapped everything up, then they got picked back up and continued and needed new plot lines. Think Babylon 5 S5
Post-Script Season is more about how the official Grand Finale takes place and then the show is renewed beyond the story they were trying to tell. Uncanceled and Revival is mostly a matter of time and distance. Uncanceled is when a show was technically set to be dropped entirely but renewed last minute, audiences may not have even notice because this all happened in between seasons. Revivals are after an official conclusion of the show and typically involve a Time Skip acknowledging the long period between the last episode and the new one. There is no hard line (revivals and uncanceled alike may have the same production team or a whole new crew), and so any given example may be all of them together.

In theory, Dexter's Laboratory could be all three tropes, despite the Negative Continuity the show has?
I'm asking this due to the recent airings of Horrible Histories on the BBC here in England.
The original ran from 2009-2013, then returned in 2015 for a new series, but The Other Wiki refers to it as both a reboot and a revival.
Equally, would this apply to Dexter's Laboratory which returned in 2001 after a 3-year gap with no new episodes (last episodes aired in 1998), but without the creator Genndy Tartakovsky's involvement, or is that Overtook the Series as well?
What's the major difference between a Revival, Uncancelled and Post-Script Season, before I add this to the work page for Horrible Histories and any other series?
I would appreciate any explanation to avoid making mistakes.
