How would you describe Revenue audit in a casino ?

I know its putting data and all that in a computer, but is it a hard job to do or just stressful sometimes? I am experienced in hotel night audit, but when I did night audit I was put in charge but I only have 6 months of experience since a day shift position opened but now I am going for a Revenue Auditor for my casino but since I couldn t find any answers if the job is a LOT harder then Night audit being I will be doing audit for the whole casino. I am not good with numbers, but I am comfortable with working with them.. I spoke with my fellow night auditors I was going for the position and they were like "Omg, that will be a hard job to do, more advanced" but what I been told is everyone has a first and can learn from scratch on what to do. I basically taught myself how to do Night audit without any help, it helped me improve my hotel skills and working with numbers. I HATE math but comfortable working with numbers as I just said. I did ask for a trial in that position to see if I can really do it but my General Manager said no because it contains confidential information hat I cannot see without the Audit title in my file. But sorry if I make it confusing but please explain to me how it is to be in a position that high then lower positions. Like I said I love jobs with a lot of paperwork because it keeps me busy and I like to be busy because then that will feel like a real job to me then working in Hotel.

Thanks in advance if you can answer my question. :)
