This is surprisingly common. WASD-biased finger positioning. Also if you only use left shift it reinforces the habit since your pinky is what would normally press the a key. If you ever fix your typing technique (or just get curious), ESDF (instead of WASD) kinda fixes this. Your same fingers handle movement, but while also using proper homerow, and you free up space left on the movement keys where you could move stuff that was on ctrl and shift to the letters. (talking about the in-game key bindings here) A few years ago I relearned qwerty with proper homerow, started using right shift, etc. I then later switched to Dvorak and then Workman. If I ever play a game I now set up the equivalent to qwerty ESDF in the controls, but with the letters of my layout. I sometimes also set backspace to jump instead of space because I use a split keyboard where I placed my space key on the right half thumb cluster and my right hand is on the mouse for games like Minetest and Xonotic.
