How often do pros play brawl stars??

I have been playing for multiple years, probably the same year or one year after bs came out and i would say i play quite a lot too but when u compare my stats to like the top players they have soooo much more wins and im thinking hows that even possible? To even play that much.. do they treat it like a job or something playing brawl stars 10 hours a day? Just wondering lol
