To be able to understand the concepts, you have to look at Newton’s Law.
First Law states that if there is no net force, then the body will move in uniform speed in inertial reference. This statement works both ways, so if it is moving with uniform speed, then there is no net force. No net force means, there might be several force acting on the body, but the total/resultant/net force of all the forces acting on that body is a vector with zero magnitude, or simply just zero.
Based on this explanations, then your statement is false. Because there might be some force acting on it, like Normal force exerted by the table to the body, and the weight of the body itself. But the net force is zero. When the net force is zero, the case will be either: no force acting on the body or total vector sum of forces acting on the body is zero (vector). Because you didn’t mention anything, we can assume the body has mass, which means it has weight, which is a force. Also because it was on a smooth surface, it probably has Normal force too.

Explanation:
Uniform Speeding on a Smooth Surface
When a body is moving with uniform speed in a particular direction on a perfectly smooth surface, it means that the body's velocity is constant and there is no change in speed or direction.
Newton's First Law
According to Newton's First Law of Motion, an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. In this case, since the body is moving with uniform speed, it implies that no external force is acting on it.
Frictionless Surface
The fact that the surface is perfectly smooth indicates that there is no friction present to oppose the body's motion. Friction is a force that acts in the opposite direction to the motion of an object on a surface. Since the surface is frictionless, there are no forces resisting the body's movement.
Conclusion
Therefore, it is true that if a body is moving with uniform speed in a particular direction on a perfectly smooth surface, no force is acting on it. The absence of external forces, such as friction, allows the body to maintain its constant velocity without any acceleration or deceleration taking place. This scenario aligns with the principles of Newton's First Law of Motion.
