This summary is not the rule. The rule text controls.
When a jury goes to deliberate on a case, they get to bring the actual evidence with them. This means any exhibits or documents that were shown during the trial and officially entered into evidence can go into the jury room for the jurors to look at and discuss. Depositions are the one exception. Those don't go back with the jury even if they were used during the trial.
The judge normally has to allow this. It's the standard practice, not something jurors have to ask permission for. However, a judge can decide to keep certain evidence out of the jury room, but only if there's a good reason for it. The judge would need to explain why that particular exhibit shouldn't go back with the jury.
For someone involved in a trial, this rule matters because it affects what jurors can physically review while deciding the case. If your case involves important documents, photos, or physical evidence, this rule generally means jurors will have hands-on access to that material during their discussions, which could influence how they remember and weigh the evidence.
