Once you create a new Event with the WordPress Editor and add an Event ticket to it, you can see that the ticket is visible on the event page of your website.

However, when you click on Edit with Elementor, and apply an Elementor template, either using the Single Event Starter Template with the Elementor plugin, or a Custom Template for Event Pages with the Elementor Pro plugin, you will be able to see that all of the event data is included in the template, except the Event Tickets block.

This is currently the expected behavior because the Ticket should be added manually using the Event Ticket widget that comes with the Event Tickets Plus plugin.
