the guy analyzes old data to train the ai to make predictions for the next matches. it's not a tactic that will always work, because in every sport there is change and development. even if there are sports with clear and definite results where this doesn't happen, you can't bet on them. what you know, the bookmakers all know.

i think it makes more sense to use ai to facilitate access, not to ask for more than you know or have access to. use your own brain instead of using ai for such important decisions.
