The expression "that's life" is used to express acceptance of a situation when something bad happens, and you can't do anything about it. It means that unfortunate things happen, and we should accept them as a part of life. You can use this expression when you encounter difficulties, failures, or disappointments. For instance, if you fail an exam, lose a job, or have a bad day, you can say "That's life" to imply that it's a part of life's ups and downs, and one must move on.
