I mean 3B is a large number ,how to design and even count them?
Well…I am really like I am five.

Well yeah, this is about the most cutting edge design and manufacturing processes in the world. So it isn’t inherently ELI5.
A modern IC is manufactured using basically a “photographic” technology (very ELI5). To get that many devices each device is really very small so the photograph technology has to be very very high resolution. The high end modern ICs don’t use visible light and uses ultraviolet lasers for this process.
Without computers, it would be impossible to design and manufacture these devices. Instead computers are used that have sophisticated design software. Designing the product is similar to writing complex computer code. This “code” is run through these programs and the programs help convert it to actual IC layouts and designs. (It is a LOT LOT more complicated than this in actuality) So we can design chips that require billions of transistors only because we’ve designed really sophisticated tools.
An analogy would be a farmer. A farmer 10,000 years ago used their hands or very basic tools – each farmer could only farm a small area. A modern farmer uses farming equipment that allows them to farm much larger areas.
