Not to besmirch 7D users, but "spray and pray" is a mainstay of action and wildlife shooting, so those users would be more sensitive to shutter life. So far, I've averaged around 1000 images per 3-5 day vacation on my 80D, and how many of those can I take in a year? For real estate, food, automotive work, etc. it's all about the composition, three shots at most per subject to extend dynamic range and maybe three groups of three just to give yourself some wiggle room in post or change the perspective. It would take me years to approach 200k shutter actuations. I've never shot a wedding, but I assume 2-3k photos is an upper limit for how many shots you can realistically compose during a 3-4 hour ceremony (without spray and pray).
Just because someone shoots several thousand frames at an event over a number of hours doesn't mean one is indiscriminately "spraying and praying."
I've shot marching band competitions where there was a different band every 15-20 minutes for hours on end. The day starts out with the smaller groups, but by the end you had 8 minutes (480 seconds) or so - the rest of the 15-20 minutes is between each performance while one group leaves and the next comes in - to try and get 2-3 sellable frames of as many as you could of the 200-250 kids on the field at one time.
It's the same thing when shooting scholastic sports. Large schools may play 50+ different kids over the course of 70-80 plays in a high school football game, and every parent who can't find several dozen of their child (who only made it into the game for one four-down series) to choose from wants to know "Why didn't you take any pictures of my kid?" And then there are the cheerleader moms who think you are there to spend the entire evening shooting hundreds of photos of their little princesses...
There are also the shooters who set up on popular "touring roads", such as an 11-mile section of US 129 near Deal's Gap,TN in The great Smoky Mountains National Park. The road is known as "The Tail of the Dragon." Sports car clubs and motorcycle clubs and enthusiasts come from all over just to ride it. During high summer, several thousand vehicles will travel over it each day. There are multiple companies that set up at various scenic curves and shoot every single vehicle that passes, post low res watermarked proofs of each frame online, and sell digital downloads, prints, mugs, keychains, etc...
This guy posted around 3,000 frames for 6/8/2019.
This company posted 2,300 frames on 6/8/2019, including over 1,100 in barely an hour as some type of bicycle rally/race went by.
There's also
this company on the same 11-mile stretch of road.
