### Is your feature request related to a problem or challenge? DataFusion doesn't have a great statistics infrastructure, which will be long project to fix. Luckily, we have begun the process to implement an extensible statistics infrastructure, and we have already merged a new low-level framework to evaluate expressions in a probabilistic context (i.e. the `evaluate_statistics` and `propagate_statistics` API introduced in #14699). The next step in this project is to switch from the old `Precision` object to the new `Distribution` object across the DataFusion codebase. This way, we will be able to use the existing mechanism around the `ColumnStatistics` and `Statistics` (maybe we should rename this to `TableStatistics`?) objects to handle statistics. ### Describe the solution you'd like Deprecating/removing `Precision`, updating its usages with `Distribution`. ### Describe alternatives you've considered N/A. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
