can 1900 test cases will run in jenkins pipeline code example

Example: what test you have on jenkins

I personally set up 2-3 jobs for automated tests
 One for smoke - > Smoke is running daily 2,3 times a day , making sure 
that all environments are up and running
- Full regression (80% automation 20% manual)?
* Before each production release(after 3 sprints)
* Only very stable test cases are stored in full regression
* Updating functionality
- Minor regression
* Runs at the end of sprint
* Tests that are related to certain modules and functionalities
* I use tags to specify which module to run
