Revenue Operations sounds like a department. It isn't. Think of it more as the plumbing running behind everything else in a company, invisible when it works, extremely visible the moment it doesn't.
Here's the short version, if you want the whole thing in one paragraph: your revenue is the output of four things happening in sequence, or failing to. Attention becomes a lead in the first place, or doesn't. A lead becomes a customer, or doesn't. The business delivers what it promised, or doesn't. And somebody tracks whether any of that actually worked, or nobody does. Marketing, Sales, Operations, Finance. Not four departments necessarily. Four functions, whether or not anyone's officially in charge of them.
Underneath those four sit three things that decide whether they hold up under pressure. Who's doing the work, and whether they know what they're supposed to be doing. Whether the process is written down anywhere, or just exists as tribal knowledge one person carries around in their head. Whether the tools in place actually enforce the process, or just record whatever happens to get typed into them.

You don't get to skip having these four cycles and three foundations. Every business has them, on purpose or by accident. The only real choice is whether you're managing them deliberately or discovering them the hard way, usually during a bad quarter.
