Alright, so most people who are talking about caps and blobs are talking about Apex armor brawling. This makes up a very small percentage of overall pvp on wormhole space. BUT, even in these apex scenarios, fleets are going to top out at ~30 people, give or take a few. At that level, every pilot is important. Not really like 0.0 space at all.
More often, you’re going to be running hank attempts on pve pilots, small gang content, or roaming k space from your chain.
Of course, the statistic variation will depend on what corp you decide to join. Suffice it to say there are WH corps who specialize in each different type of pvp. Want to do lots of apex brawls? There’s a corp for that. Want to be a nano kitey boy? There’s a corp for that. Want to gank carriers in nullsec all day? There’s a corp for that.
Pick one and have fun!
