Yes, the Devas, Bhutas, and others are lower divinities compared to Lord Krishna.
This is explained by Krishna to Arjuna in detail in Chapter 7 (Jnana Vijnana Yoga - Knowledge of The Ultimate Truth). I've quoted a few verses below.
bahūnāṃ janmanāmante jñānavānmāṃ prapadyate
vāsudevaḥ sarvamiti sa mahātmā sudurlabhaḥ 7-19
At the end of many births the wise man comes to Me, realising that all
this is Vasudeva (the innermost Self); such a great soul (MAHATMA) is
very hard to find.
kāmaistaistairhṛtajñānāḥ prapadyante’nyadevatāḥ
taṃ taṃ niyamamāsthāya prakṛtyā niyatāḥ svayā 7-20
Those whose wisdom has been looted away by this or that desire, go to
other gods, following this or that rite, led by their own nature.
yo yo yāṃ yāṃ tanuṃ bhaktaḥ śraddhayārcitumicchati
tasya tasyācalāṃ śraddhāṃ tāmeva vidadhāmyaham 7-21
Whatsoever form any devotee desires to worship with faith — that
(same) faith of his I make (firm and) unflinching.
sa tayā śraddhayā yuktastasyārādhanamīhate
labhate ca tataḥ kāmānmayaiva vihitānhi tān 7-22
antavat tu phalaṁ teṣāṁ tad bhavaty alpa-medhasām
devān deva-yajo yānti mad-bhaktā yānti mām api
Endued with that faith, he engages in the worship of that DEVATA and
from it he obtains his desire-fulfilments; all these being ordained,
indeed, by Me (alone).
antavattu phalaṃ teṣāṃ tadbhavatyalpamedhasām
devāndevayajo yānti madbhaktā yānti māmapi 7-23
Men of small intelligence worship the DEVAS, and their fruits are
limited and temporary. Those who worship the DEVAS go to the planets
of the DEVAS, but My devotees ultimately reach My supreme planet.
