Retrieve a large amount of data for ML proyect

Hello Devs
I’m currently working on a Machine Learning project (for my Master’s Degree) with the main goal of implementing an algorith which improves the matchmaking methods in online games.
The techniques involved includes bayesian networks, classification algorithms and neural networks.

For this purpose my team needs a large amount of player statistics (time played, K/D, level, etc.) and i was wondering if there is any chance to get this information for games like CSGO, Overwatch, Valorant, etc.
I’ve been looking in many places but no luck yet.

The dataset will also work for us to develop a java project to analize the present information and extract all kinds of features related.
