The fashion and travel industries are much bigger than the gaming industry, their content is way easier to monetize. The only reason gaming works at all is that it is so ridiculously cheap to do.
So there is no way to "solve" this, the people who wants to be influencers wants to live a top 0.1% lifestyle traveling and testing new fashion everyday, that just isn't feasible for everyone who wants to try. The nerd dream of sitting at home all day playing games is so much easier to reach, which is why you can see so many people playing games for a living, not because it is easier to make money do it.
