There are pictures on the ticket(s).

At the drugstore, people can also buy tickets for the California State Lottery. They pay one dollar for a lottery ticket. There are pictures on the ticket. Some pictures are winning pictures. And some pictures are losing pictures. Most people win nothing. Some people win two dollars. A few lucky people win thousands of dollars.

(True Stories in the News, Sandra Heyer, Longman)

In this sentence There are pictures on the ticket, I wonder if the ‘ticket’ should be in the plural form ‘tickets’, or if both ‘ticket’ and ‘tickets’ are correct.

Re-read the sentence before the one you asked about. Is it clear now?

Thanks, GoesStation.

Now I understand ‘the ticket’ refers to ‘a lottery ticket’ in the previous sentence. But I think maybe it’s better to add a word ‘different’ before the word ‘pictures’ like this: There are different pictures on the ticket.

It's not necessary. From the wording and context, we can assume that the pictures are different. You choose the picture you like and scratch it.
