Hey @prashant007,
The community has a section on interesting ML use cases: Data Science - Alteryx Community.
Alteryx can do a wide variety of ML tasks both unsupervised and supervised. A great place to check for easy use cases is the examples on all the predictive tools. Another place to check is the predictive example workflows.
One of the example workflows predicts which people to target for there next marketing campaign.
In the ARMIA forecasting tool example it forecasts future bookings.
