It’s worth noting there’s a difference between a heckler video and a crowd work video. If the performer solicits audience participation, that’s not them being heckled.

That said, many comedians do several shows a week, some even doing multiple spots a night. These days, most of them record their sets - and the audience, to a degree. When they amass so much footage, it’s easy enough to have a video now and then involving a heckler.

Of course, sometimes, some things do get ‘scripted’ with the audience. This is a funny example of a bit Gianmarco Soresi did using the audience to get this clip parodying a Rocket Money ad.
