Help with Canon - focus issues

I hate my Canon 60D.  For the life of me, I cannot get it to focus all the way on everything in a picture.  I know I can depress the shutter button a few times and get it to sense what it should focus on but it's never right.  When I use the self-timer and remote, almost all of my photos are blurry because it doesn't focus on anything.  I have beautiful family pictures taken at Christmas that are useless because it didn't focus on anything at all when I used the remote.

At this point, I'd be happier with iphone X pictures than I am with this camera.  I bought it when it first came out and I've read books on it, taken online classes on it and even googled how to get better images with it.  I've switched lenses and I still have the same problem.

I want to replace it with a cheaper Canon EOS camera but before I do that, I thought I'd ask to see if I'm doing something wrong.

How in the world do I get this camera to take a picture where the entire frame is in focus? My old Canon Rebel would focus on everything in the frame, similar to just a point and shoot.  Loved it but I just had to get an upgrade...and now the older Rebel is dead.
