New camera

I've been thinking about getting a mirrorless camera for some time now. I have a DSLR, but it's old and there are scratches on the lens- basically worthless. I've been meaning to take some online photography classes and improve my photography skills, but as of right now, I don't have a proper camera. Since this is something I've been really looking into, should I just bite the bullet and buy a new (expensive) camera?
