It’s hard to say, I’m not from Asia so I’m not familiar with pirate software. I do know the good whiteboard software, with a huge variety of music, animations, characters, etc., isn’t cheap.
I also know that buying software doesn’t mean you can use it. I took Photoshop and Illustrator classes in college, I’m useless with them. The only thing I can do in Photoshop is making a picture black and white, crop, etc. But I can’t draw, even the magnetic lasso tool is a struggle for me. I don’t know if those who do whiteboard videos ever go on illustrator or photoshop for specific things, but it seems to me whiteboard requires a lot of different skills.
P.S. How come you have a Texan accent if you live in Bangladesh? Are you an American expat or a Bangladeshi that was born in Texas?
