This is exact definition of RTS - "Real-time strategy (RTS) is a subgenre of strategy video games where the game does not progress incrementally in turns". Anything else is just your personal opinion/preferences.
In general, yes.
In details, RTS(real time strategy) and RTT(real time tactics) are not the same, but RTT is a sub genre of RTS.
In RTS you always have resource and base management, even if limited, you still need to accumulate resources and produce new units to achieve victory conditions.
In RTT, which battlefleet gothic and total war is there is no element of resource management, you have a set amount of units which you pre-define before the battle and it is all you get for the game, no resource management, no base management, no macro element, which is mandatory for true to genre RTS game.
So to sum up, RTT game is part of RTS ganre, but RTT games are NOT RTS games.
In RTS you focus on building right composition and accumulating resources for more units and using them correctly aka micro+macro.
In RTT you focus exclusively on battle tactics aka micro only and often in much more limited way then in proper RTS game.
