In most countries, yes, international cards on the major networks work at ATMs without drama, especially machines belonging to established banks. The practical issues are not whether it works but what it costs and where. Expect up to three separate charges: your home bank's foreign transaction fee, a possible fee from the ATM's owner, and the exchange margin. A card designed for international use can eliminate most of this, which is why many expats get one before flying.
Two habits will save you money and grief. First, when the screen offers to charge you in your home currency instead of the local one, refuse it; that conversion option is consistently a bad rate. Second, use ATMs attached to actual bank branches rather than standalone machines in shops and tourist strips, which charge higher fees and carry more skimming risk.
Also tell your bank you are abroad so fraud systems do not freeze your card, know your daily withdrawal limit, and carry a second card stored separately.
