Not necessarily. It's about timescales and other environmental factors. Pausing in a debugger is measured in seconds. Your network-using application won't notice extra half ms for a print statement, but might change its behaviour if you pause it for 5 seconds, as requests will timeout. A video game running in fullscreen won't mind printing to console/file in the background, but may not handle well being interrupted in the middle of rendering and having you switch focus to the debugger (less of a problem these days, but I remember this being a pain ~10 years ago).
