From experience, that's not true. Things typically go wrong when something changes, or more rarely when something runs out of space/memory. Big cloud providers change stuff all the time, and typically do break things now and then. When they do all your can do is wait.
If you're using your own servers, or even VPS, you do have control over infrastructure, and can plan for changes and mitigate problems quickly, and you can run for years without downtime if nothing is changing significantly. Depending on your staff, funding, etc that might be attractive or not. Each has its own advantages, and disadvantages.
