Other section in my mac is too big

Looking in this method is often misleading and not accurate. Suggest Rebuild the Spotlight index on your Mac and then check again. It may reduce.

But, if this does not reduce, refer to this See used and available storage space on your Mac and especially this portion and that is the final word on managing the " Other " Category from Apple

• Other: Contains files that don’t fall into the categories listed here. This category primarily includes files and data used by the system, such as log files, caches, VM files, and other runtime system resources. Also included are temporary files, fonts, app support files, and plug-ins. You can't manage the contents of this category. The contents are managed by macOS, and the category varies in size depending on the current state of your Mac.

Did not work and in what way ?? Do you mean the usage did not come down ?? If that is so, the suggested methods to verify did confirm the " Other " category represented in you screen shot is accurate.

It further confirms what Apple has said - can not manage this category only the OS can. Hard fact but the only way I know to reduce the Other is the reset the computer and then be very selective as to what is installed.
