I wanted to get some insight from others on if this is true since I can't find a good answer on the IRS website, and if it is true why does anyone want to gain real estate professional status?

Quote from @Zachary Jensen: Quote from @Bernard Golden: Looking for recommendations for a time tracking app suitable for real estate professional status qualification.

Am interested in a copy of a professional log book as well...thank you...

That's true regardless of whether you have REP status. 

Any recommendations on the most efficient way to track your time when classified as a real estate professional?

2) The minimum hours required are 750 hrs, but if running a short term rental, 100 hrs is supposed to be adequate, is that still true ?

Check with your trusted tax professional. 

@John Zhang If your wife qualifies for Real Estate Professional Status (REPS) and materially participates in managing rental properties, there is no limit on the amount of rental losses, including depreciation, that can offset your W-2 income.

I do not know his entire situation, this is true.

These are professionals with additional training and a stricter code of ethics.
