Do you guys consider all mechs titan mechs or just the 4 that are called titan mechs

I have 3 of the 4 titan mechs. I have Lloyd's titan mech, Jay's titan mech, Zane's titan mech, and I just need the newest one Coal's titan mech but iv seen people refer to all mechs as titan mechs. Now the problem I have with that is I feel like the titan mechs are called titan mechs because they are a bigger robot mech suit for that one ninja and yes you could argue the new samurai x mech is a titan mech but the problem I have with it is it isn't for a ninja it's for nya's alter ego samurai x. Well that's yhe and of my rant feel free to share your opinions on it
