The AVCHD standard for 1080p specifies a peak data rate of 24Mbit/sec, equivalent to 8MByte/sec. At that rate 32GB would hold about 66 minutes of video. But it's unusual for a video clip to require such a high rate continuously, so you'll almost certainly get a lot longer than that. As an example, camcorder manufacturers indicate a capacity of about 3 hours when recording high-quality 1080p to a 32GB card.
... 1080p50/p60 production format will require a whole new range of studio equipment including cameras, storage and editing systems, and contribution links (such as Dual-link HD-SDI and 3G-SDI) as it has doubled the data rate of current 50 or 60 fields interlaced 1920 × 1080 from 1.485 Gbit/s to nominally 3 Gbit/s using uncompressed RGB encoding...
In the page they tell of 1080p that can use more than 3Gb/s for data streaming. So if we assume that you will need 3Gb/s, you divide bits by 8 to get bytes: 375MB/s. So we can assume that your 32GB will last about 90 seconds before runnning out of memory. Well we need some pro advice on that!!
The high bitrates you quoted come from the video production section of the article. That's because the people who create films capture video using lossless recording formats. Those formats require very high bandwidths and a lot of storage because they literally keep every bit intact. But once those movies are edited and distributed, they have been transcoded into lossy formats that require far less storage and bandwidth.
Consumer video cameras generally use the AVCHD standard which is a lossy compression format. It specifies a maximum bitrate of 24Mbit/sec for 1080p30 and 28Mbit/sec for 1080p60. See: http://www.avchd-info.org/format/index.html
The content recorded on Bluray discs has similar data rates.
