Thanks for the interest in WooCommerce Tickets.
WooCommerce Tickets creates a special Product to purchase Tickets with using WooCommerce. So any payment processor show work including 2checkout and paypal.
I would recommend looking over our New User Primer for WooCommerce Tickets to see how it all works:
https://theeventscalendar.com/support/documentation/wootickets-new-user-primer/
But yes you could use it to register for specific events.
We do have a front end demo here:

That you can check out.
Let me know if you have any follow up questions.
Thanks
