Essentially, yes. Nothing is majorly contracting it thus far.
In Pennyworth's case, it didn't get the ending it wanted to explain how Samantha is out but Bruce is born, because it got cancelled. Maybe we'll get that story told some day.
(Little things like Lucius and Alfred knowing each other 20 years prior or how Sid Onslow apparently betrays and gets killed by Alfred, as alluded to all in one scene of Gotham, doesn't really matter and might have been part of that incomplete story they had planned out. It happened offscreen at this point.)
Pennyworth is absolutely the same universe as Gotham. As for Gotham Knights, it has many visual connections but it's not that straight forward. We'll just have to see if it connects or contradicts anything, but it's definitely set in the same "Gotham" so to speak.
