Yes. That's one way. It works fine if a person knows enough to find that board on AliExpress and buy it and is able to gather the resources to get themselves started with it. (I, myself, typically use cheap no-name dev boards...but I've been around the block a few times.)

Another other way is a ~$100 Arduino starter kit. It includes a printed instruction book and enough useful parts to sit down and begin doing stuff immediately. Anyone with a sufficiently-large pocketbook can buy it for themselves (or for someone else).

One of these things is like buying individual Lego bricks, or maybe lumber and fasteners from the hardware store, with a specific goal in mind. It's creative by necessity, and for those who know how to get where they're going then it's really quite lovely to have marketplaces like AliExpress and Ace Hardware available to satisfy our whims.

The other is more like a buying a packaged Lego kit or Meccano or an erector set that includes instructions for building several different things using the included parts. If a person (including a child) doesn't yet have any idea how to get started, then this can help them get the clues they need to go further with building other things.

I could buy a Chinese D1 mini dev board and a bag of assorted resistors, LEDs, transistors, and a breadboard and put it all in a nice box and give it to a kid, but I expect that they'll have a hard time figuring out what comes next. ["Now just draw the rest of the owl."]

Or, I could buy an packaged Arduino starter kit for a kid and have a reasonable expectation that they'll soon be telling me all about the neat -- if simple -- stuff they've done with it. They might not even realize the things they've learned along the way, but it'll stick with them well-enough if they want it to. And then they can move on to using VS Code with PlatformIO and start hammering out RP2040 PIO assembler when that time comes. If that's something they choose to be interested in, then they'll have a good foundation for the independent projects that may come later.

The whole is sometimes greater than the sum of its parts.
