Schools often have very old computers but don’t let that discourage anyone. We had old Apple IIe’s in 1998 in my high school “computer literacy” class. I became a programmer in part because I was bored and learned BASIC on the Apple II’s and my TI-85 calculator also supported BASIC.
Sometimes, a crappy computer teaches you more than a modern one. (Only if you want to be a programmer, though. Don’t learn Office 2000 because politicians in your country won’t budget for some cheap, modern laptops.)
