Need Advice! I have zero coding exp and want to learn SQL and Tableau and hopefully develop software in the future. Should I buy a MAC or PC?

I got advice that a good way to break into software development is to start with learning database like SQL and also Tableau to get my foot in the door with a job. While working in database, learn the stuff required for writing software. Does this sound like a good plan? Do you think its better to learn everything on a PC or a MAC? Thanks so much!!!
