Not necessarily? Most of us don’t make most of our money through command of capital, so we aren’t capitalists in that sense. Far more are probably capitalists in the sense of liking capitalism and more-or-less promoting it, specifically, but that still may not be most, let alone everyone.

Anyway, markets and investment pre-date and are not identical to capitalism. Working in and among those (“yet you participate in society. Curious!”) does not imply love of those things, nor even does appreciating or being a fan of markets and private investment require one count oneself a capitalist in an ideological sense. They’re not identical.

I'm not a capitalist for sure :P

But I'm a salarized employee at a traditional tech firm :)
