Do I need to pay a deposit to stay in a hotel in Europe?

No deposit has been paid in advance, and more is international credit card guarantee.

That is, use your own international credit card when booking, such as VISA card, MASTER card, American Express card, JCB card, etc. I usually use VISA. On the day of booking, the usual situation is that the hotel may charge you for the first night of your credit card (which can also be understood as a deposit), which involves a subsequent cancellation problem.

After booking, the hotel will give you a confirmation form, and the cancellation period will be written on the confirmation form. Different hotels have different cancellation periods, usually 7 days, 14 days and so on. If you cancel before the cancellation period, the hotel will not charge you any fees, and the reserved money will be returned to you. If you enter the cancellation period, you will be charged according to the terms of the hotel. Some special rooms are irrevocable, so you should read them carefully when booking.

After checking into the hotel, the hotel will let you go through the check-in formalities with the credit card of the reserved hotel and put it at the front desk. When you check out, the hotel will refund it to you to ensure that the hotel can deduct the extra money except other room rates, which is the deposit you mentioned.

This is the specific situation. I didn't eat lunch and have been typing. I hope I can help you, haha.
