Does the cost of the trial by jury equal more than the $100 cost of the ticket? After all, jury deliberations take more than a day, and they need housing and other accommodations while under the care of the court system. The plaintiff can still request a judge's ruling on the decision should they choose. In the case of misdemeanors or civil suits, I'd say that the minimum bar for a trial by jury would be that the damages in question amount to at least the cost of the jury trial. For misdemeanors, this is specifically those tied to fines (which most are).
Do you mean the jurors or the lucky ticket-holders?
Around here they have you come in for jury duty (hope you have a car since it's halfway across the state and there are no buses or trains from nowherevilles), and then you sit for a few hours, and then they dismiss you without selecting you for a trial, and then you have to drive back across the state.
If they select you for a trial, it doesn't last more than a day.
If it does last more than a day, they don't have housing for you, they just require you to come back every day. And maybe you want to get a hotel room instead of driving back and forth, but you don't know you'll need to until you've finished that day's jury duty, and you don't know how long the trial will go, either!
If you meant the ticketed person, "they need housing and other accommodations while under the care of the court system" is an odd way to say "throwing the ticket-holder in jail," which is a thing that happens (particularly when they have a warrant for unpaid tickets, generally because they're too poor to pay, they need to use their money to pay rent, utilities, maybe to eat if they don't have food stamps or they don't cover enough, etc, and the tickets keep accruing interest while they're unpaid, etc).
