Question about Ubuntu 64-bit support

Recently I have installed Linux Ubuntu on my mom’s computer, replacing the old Windows XP. Seems enough for googling and mailing that she is doing. BTW, it works just fine after few small tweaks, like getting rid of too-fresh Unity interface and disabling awful overlay scrollbars (that appear only when you mouse over the edge of a window). Anyway, in the process, I had to read some information about Ubuntu and one of the questions was – whether to install 32-bit or 64-bit one. Jumping to the end – I installed 32-bit, to exclude any possibility of applications/drivers incompatibility (search it and you will see many problems with 64-bit Linux installations, old ones and new ones). In the process, I came to the Wiki page, explaining the difference. The thing that I did not understand is the strange claim “As Ubuntu is entirely open source, […] all hardware supported by Ubuntu works equally well in 32-bit and 64-bit environments”. Please someone explain me how the “open source” is connected to ability to “work well” in 64-bit system? For those who do not believe (and I wouldn’t myself if I heard that), here is a screenshot:

If one is simply emailing and doing light web surfing and switches to Ubuntu, what does one do if things go wrong. Say data or an email file is corrupted, how is that fixed? Or is it the fact that such an error would never occur under Ubuntu. I guess I'm just trying to understand why someone like me, who is new to open source, should embrace the "new" over the "familiar". Sorry I could not help with your query. It's just that in my research into O/S, I seem to read about Ubuntu's ease of use, but never read "why".
