Hey there Lorena, thanks for getting in touch!
We do have a Community Events add on that allows users to create and publish events. We also have add ons for a number of ticketing integrations with Eventbrite, WooCommerce and others. However, we don’t currently support a way for users to publish an event and create tickets in the way you’re looking for.
This is a feature that has been suggested. I would definitely encourage you to add your vote because we check frequently for ideas of what to include in future releases.
Does this answer your question? Please let me know.
Cheers!
Geoff
