I’m new to Machine Learning and I’m a bit confused about how data is being read for the training/testing process. Assuming my data works with date and I want the model to read the later dates first before getting to the newer dates, the data is saved in the form of earliest date on line 1 and line n has the oldest date. I’m assuming that naturally data is being read from line 1 down to line n, but I just need to be sure about it. And is there any way to make the model(E.g Logistic Regression) read data whichever direction I want it to?

A machine learning model in supervised learning method learns from all samples in no order, it is encouraged to shuffle the samples during training.
Most of the times, the model won’t get fed with all samples at once; the training set is split into batches, batches of random samples or just in whatever order it is in the training set.
