Yeah, Trump is undoubtedly thankful for the hacks and the information campaigns, including the recently revealed funding of the likes of Tim Pool. I've seen various opinions attributing Trump's most recent win to the rise of influencers and podcast creators who presented themselves as an alternative to the traditional media. You're right about the other countries too. Having the likes of Schroeder or Le Pen on the payroll goes a long way, and that's not the limit of the extent of the Russian operations.

Edit: Grammar.
