I'm not fully convinced that some basic offline trades will become saturated even if common

Just because many learn a skill does not necessarily mean there is no need for it or opportunity. Demand can vary depending on location, industry trends and types of customers/jobs. As long as population growth and infrastructure development continue, there will be maintenance and repair work of some form. A skill itself may not become truly "saturated" as long as diligent professionals help it evolve to remain relevant.
I'm curious to hear others thoughts on where exactly the threshold of being a "saturated" skill lies.

Need i talk much? When too many people are learning a particular skill, there would be intense competition in that sector in the long run. Somehow, the variables like population growth and location can give opportunity to everyone, but it would be difficult for someone to become rich in that particular skill because of competition.

True, let's take graphic designing for instance, on a daily, weekly and monthly basis one or more persons come in to learn graphic designing. While we have thousands of graphic designers, there is still more than enough work to go around as long as you are good at what you do.

That's very right my friend. Some ventures are not entitled to saturation levels.
