How much data does OneDrive collect?

So I have been using OneDrive for about a year and a half mainly just to ditch Google Drive. I know that OneDrive does collect data but I'm not sure how much. I have been slowly migrating my files to an external ssd and some flash drives. I'm already ditching OneDrive due to those concerns. Is it like Google where they scan your files for keywords to sell to advertisers or something else?
