The good news is you haven’t brought all your things in yet. Don’t bring anything else in until you’ve had some time to investigate.
One bed bug, like you’ve said, could come from anywhere. If this apartment is infested you will find so many more. Give it some time to make sure this is an infestation. Do you have bites? Are there other signs? Of course the landlord is ALWAYS going to say there aren’t any bedbugs, of course they would. But give it some time, pay another month, see what happens.
If no more bedbugs show up, and you don’t get bites, go ahead and move your stuff in. If it’s infested, get out because they are SO hard to get rid of!
Looking past the caption, I think it’s way funnier when you realize the cat doesn’t actually know how to read. He thinks these are huge cans of cat food.
