Bottom Bracket Compatibility

Hi folks,
I bought a bike with a Tiagra Groupset, and a pressed fit bottom bracket in 2021 - a Cube Attain Race.
I was thinking about upgrading her to 105 as a winter project - buying parts off a damaged bike or similar. The bit that is troubling me is bottom bracket compatibility - there seems to be a million different standards.
If the bottom bracket of the bike I am purchasing them from is not a pressed fit, it is a BSA or something else, am I likely to end up with a crank-set that doesn't fit my bike.

As an aside, if you are upgrading to 105, you can buy new parts and full groupsets for pretty good prices now. A full 105 rim brake groupset will come in at around £400 which is probably the best value value on the market nowadays.
