That's completely false and dangerous to think. Even said manufacturers of motorcycles equipped with six axis IMU for ABS and traction control specify this in their user manuals.
You have configurable levels of TCS on modern motorcycles, because what the electronics can't know is the current difference between static and dynamic friction. That depends on what tires you have, what pressure and temperature they are at, the road surface composition, temperature, water presence. There's also suspension and road imperfections and other things.
The difference between static and dynamic friction is critical in deciding when the electronics need to intervene. For dry perfect asphalt the maximum traction is at 14% (if I remember correctly, exact figure not important) wheel slip. Meaning the wheel is accelerating/decelerating 14% more than the bike. Any less and you lengthen the stopping distance or losing acceleration. Any more and you risk crashing. On water though the difference between static and dynamic friction is very large. Once a slide begins the available traction goes to almost nothing compared to before (I think 30%) and you are in for a bad time. An simpler example is road bumps. There's nothing the electronics can do if you wheel leaves the ground because your suspension can't cope.
In MotoGP in addition to the six axis IMU they also have GPS and the values in the electronics are set manually for each turn depending on what the conditions they expect to find there at that time. And they still have both highsides and lowsides! Reality is extremely resistant to being perfectly modeled in computers.
