Advice needed for PowerBI and DAX

Hello community, Hope you are having a wonderful time.

I started learning PowerBI and DAX as i feel this is probably the one i haven't tried. I already have a pretty good knowledge of Excel, Python - Pandas,numpy,etc.,

My current work revolves around data analysis and insight generation from one or the other way from a ton of data thrown at our team.

I haven't tried Tableau yet (don't know how much it's used across industry, any idea about it, please share, much appreciated) but yes, I worked in Google data studio before (made projects during University).

What are the pitfalls i need to avoid learning these tools. How widely are these used in companies, and any general thoughts about PowerBI or other platforms you use for Analysis visualisation and dashboard building which are popular or used in organisations!

Regards!!
