In a simple linear regression setting, the probabilistic model equation allows for some deviation of the points about the regression line, making it a more practical model.

This is true. The probabilistic model equation includes an error term that accounts for the deviation of the points from the regression line. The error term is assumed to follow a normal distribution with a mean of 0 and constant variance, which allows for a range of possible values for each observed point. This makes the model more realistic, as points in real-world data tend to have some level of variability.
