Fuel prices were absolutely an issue for Concorde. BA struggled immensely with the Arab oil embargo and the per-seat cost for the Concorde shot up into the stratosphere and ticket sales collapsed.
At todays Jet 1 A US fuel price of $3.07 per gallon it would cost $108k to fill the Concord. Which holds 120 passengers. That comes out to a cost of $900 per person passenger on a full fight.
If the cost of fuel were double like a few months ago then that cost would be $1,800 per flight.
Compared to a Boeing 737 which has a fuel cost of ~24k at max capacity of 7,878 gallons at todays prices. A passenger limit of 177 and a fuel cost as low as $136.64 per passenger on a full fight.
Meanwhile a one way ticket cost US$975 in 1977 or inflation adjusted about 4,700$ today. Which increased faster than inflation so by mid 90’s your talking around 6,000$ which is something like 12,000$ today.
Thus fuel while expensive wasn’t a deal killer over most of it’s history as long as they could keep most seats filled.
The "as long as they could keep most seats filled" was a deal killer though.
There was enough demand for one return flight a day carrying a small proportion of the overall passengers on the immensely-popular with wealthy people JFK-LHR and JFK-CDG routes. That wasn't enough to utilise the 14 production aircraft properly, never mind enough demand for it to have been viable as an airframe programme ...
They both also used it for private charters which was apparently quite a profitable business. Anyway, the exclusivity was presumably more profitable than simply maximizing occupancy.
That said, boom is building a significantly smaller aircraft which should again open up more possible routes.
The Arab Oil Embargo was 1973-1974 and the Concord didn't go into commercial service until 1976. While it sounds like the oil crisis had an effect on airlines placing Concord orders it didn't overlap with the commercial service being offered to the public. See:
The oil embargo hit the entire industry hard, but Concorde continued operation into 2003. Over time as other aircraft became more efficient the efficiency gap grew much larger but it was still profitable up to Air France Flight 4590.
Concorde survived on government subsidies, especially with the R&D costs, but also the maintenance chain. It was a point of national pride for the UK and France, but also a money pit for both countries.

Yes, and this was mostly necessary because of the small unit counts and small number of routes, not because of fuel costs (though the latter certainly did not help.
Both could be significantly better with Boom: more routes, and lower fuel costs.
