Nah. Chinese submarines aren't that quiet so if there were any in the area then the US Navy would have them localized already and there's no sign of that. And Chinese subs lack the persistence to stick around without support for long. The reality is there are zero Chinese subs anywhere near Venezuela.

Submarines needing support isn't theoretical.

Now who is speculating?

Support ships are not speculations.

A speculative deployment is.
