Exactly. That's why I roll my eyes every time somebody says we need to prioritize Voter ID laws. The percentage of fraudulent votes that are cast by people showing up at polling places is very, very tiny. For absentee voting no ID is needed at all, nor is there any state I'm aware of that requires any kind of ID to register to vote, so there is simply no limit to the large-scale vote fraud that's accomplished via absentee ballots.

Why the heck would any vote fraud perpetrating organization waste its resources trying to get hordes of actual people to physically go to multiple polling places or even go to one polling place if they're not legally eligible to vote? Any effort to use actual people voting in person would carry an extremely high risk of a few of the people who were recruited turning informant, and landing the fraud organizers in prison.
