It is not possible for IT Pro TV to offer a legitimate CSM course. This is because the CSM requires that you “attend an in-person, two-day (16 hour) CSM course taught by a Certified Scrum Trainer® (CST®).” The cost of an in-person course is often around $1,400.
Originally, the CSM didn’t even require a test. Once you took the two-day course, you were certified even if you daydreamed the entire time. Now after taking the course you have to get 37 questions right on a 50-question test.
The Scrum Alliance recommends that you “familiarize yourself with the Scrum framework” before attending their two-day CSM course. You can do that by watching IT Pro TV’s Agile courses you mentioned above. After doing that, your best bet for obtaining the CSM is to ask your employer if they will pay for you to attend an official CSM course. Many companies will, as long as it’s related to your job.
A popular test-based alternative to the CSM is Scrum.org’s Professional Scrum Master I (PSM I) certification. The cost of taking the certification is $150. Professional Scrum Master certifications “are lifelong and do not require any additional payments or renewals.”
There is a course request for “Professional Scrum Master Level I (PSM I)” near the bottom of IT Pro TV’s Course Request page. I recommend voting for it and subscribing to it. The URL is https://app.itpro.tv/course-request/
