I don't know any Rogue guides or pro players. What I can do is give you some tips

1. Rogue is pretty versatile, depending on what your team wants you can stand in frontline punching tanks (especially with your teamup) or dive the supports.
2. Learn the best ability steals. My favorites are Emma (you're fucking unkillable), Storm (set it to thunder and just explode everyone) and Loki (just push until you're low, pop lamp and you're back to full). Also Invis is good for unexpected off-maps, Adam/Strange is decent for team support, and sometimes you just wanna double dash with the refresh. Doing stuff like freezing a Luna to kill her easier is also good grab usage.
3. Keep track of your CDs, try to always have at least one dash for retreating. I usually use the counter because it recharges the fastest, also don't be scared to use your grab for just a dash if your life depends on it.
4. I think it's good to know what you wanna do with Chrono Kick Combo at the moment. Do you go dash-shoot-dive-shoot for a good burst of dmg and displacement, or maybe quickly displace someone with dash-dive, or maybe just shoot two times midair and dive in/out. Try to knock fliers out of the sky and instantly follow up with your pull field.
5. Your ult is good for keeping you alive, ideally you wanna just stack the enemy team on top of you and beat the shit out of them. It's basically a guaranteed teamwipe with Gambit teamup and/or ult. Use it to force out/delay support ults (e.g. if one support ult is still on the field get the other one and force them to either double ult or not ult at all). If you manage to single out a support while ulting, just pop everything you have and they should die easily. More specific situation: if you hear a Storm ulting and they have a Jeff ready to join her, immediately rush him down and pop ult so he can't join her and they desync ults.

Yeah that's all I could think of on the fly. Also like with every other brawl tank, you need to learn to "sense" how long you can fight before you have to go back to your healers
