Does this shortcut work the same way in every app?

No. The listed contexts include ChromeOS Flex / Stable, Google Chrome, Photoshop, Microsoft Teams, Microsoft Outlook, Adobe Lightroom, Cursor, Obsidian, Mozilla Firefox, Microsoft Edge. Check the table for each application and platform: the active window, keyboard layout and application settings determine which command receives the key press. An application being available on an operating system is not evidence that this exact binding works there.

What should I use on a Mac?

Use a macOS binding shown in the table, if one is recorded for your task and application. This page does not assume that replacing Ctrl with Cmd produces a working Mac shortcut. When an equivalent has not been independently verified, open the linked application reference and check its documented context before relying on it.
